Your corporate network is down due to a critical update. How do you restore connectivity at multiple sites?

Primeiro deve se analisar que atividade comprometeu a minha rede, caso de exemplo: a mesma foi devido uma atividade programada e a falha foi durante a execu??o, diante do ocorrido de imediato vamos fazer um rollback da atividade para que o sistema e rede se reestabele?a de imediato, evitando assim um alto indice de reclama??es e perda de receita, depois vamos analisar o que pode ter ocorrido durante a atividade e efetuar as melhorias para que n?o ocorra novamente.

I would like to point out that before every update (especially critical) a test run has to be made. Firstly we test the update at a dmz or a off-network stub and then we continue with the whole network. Even then the update has to be done branch by branch. If however the update has been done, the first action is a immediate rollback to a functioning environment.

First of all you need to check your entire network systems. If you have an NMS verify the alarms to in order understand where the update failed. Once you identify the issue. Apply your BCP and open a bridge phone call or collaborative app that will help to apply your CMP. Do your rollback…!!!

It is necessary to check what was the impact, whether the update stopped only part of the network or an isolated part to know if the impact was large, involving a much larger region. The Network Operation Center team should take action, check the entire network management, analyze each equipment that may have been impacted by the update, the work involves checking alarms, logs, if there was only one network update, take action immediately, rollback the update to the version that was working before, inform the supplier about the problem happened, trigger the technical support team and request a correction of the update made, just do a new activity after being sure that the update worked well in a controlled environment.

first step is to determine the scope of the outage. Check your network management system (NMS) for alerts and logs that can pinpoint where the update failed. If the NMS is down, you'll have to manually inspect network devices like routers and switches. Communicate with site managers to understand the extent of the disruption. This information is crucial for prioritizing recovery efforts. Remember, it's important not to rush, as a hasty fix could cause further issues.

Network outage caused by a critical update, clear communication is just as important as fixing the issue. I will immediately communicate the situation and our resolution steps to stakeholders - management, IT staff and end users. We create transparent channels through email, messaging systems like MS Teams or phone trees. Regular updates manage expectations, build trust and maintain order during a crisis. In the absence of facts, assumptions multiply. So get ahead of assumptions with a comms plan to the stakeholders.

While working on the permanent fix, consider implementing temporary solutions to restore basic connectivity. For instance, set up backup internet connections or mobile hotspots at key sites to provide interim access. Deploy temporary network configurations or reroute traffic through alternative paths if feasible. Communicate these temporary measures to stakeholders to ensure they know how to maintain productivity during the outage. This approach helps reduce the impact of the disruption and keeps operations running as smoothly as possible while you work on a long-term solution.

Para restaurar a conectividade da rede corporativa após uma atualiza??o crítica que a deixou inativa, é essencial ter um plano de comunica??o bem estruturado para manter todas as partes interessadas informadas sobre o andamento da situa??o. Aqui est?o algumas diretrizes para elaborar um plano de comunica??o eficaz: 1. **Identifique as Partes Interessadas:** Liste todas as partes interessadas internas e externas que precisam ser informadas sobre a situa??o, como membros da equipe de TI, gestores, funcionários e fornecedores de servi?os. 2. **Defina os Canais de Comunica??o:** Escolha os canais de comunica??o mais adequados para cada tipo de público-alvo, como e-mails, mensagens instantaneas, reuni?es.

It's regrettable thing, that, the damages caused by the outages / breakdowns of communication system is so-much damaging, and the losses are irreversible. And, the most regrettable thing, is that, the Corporates' Crisis Management Team takes no caring of taking all the stake holders - Customers, Vendors, Shareholders/partners, into confident. It's the team work of all the stakeholders, would win, any crisis, and make the organisations survice, and flourish forever. The miscommunication creates the lowering of trust, among the stakeholders. It's very much for the better-future of the organisation, that, all the stakeholders must be continuously updated, of the latest developments, till the system is set right ?? %. Team Wins, Always!

Before rolling back, isolate the affected areas to determine if the update is indeed the cause. Test individual components or configurations in a controlled environment to confirm. This step involves setting up a test network or using staging environments to replicate the issue. If the tests confirm the update's role, then proceed with the rollback. Isolating the issue helps ensure that the rollback is the appropriate solution and prevents further disruption by addressing the specific problem accurately.

I agree, that, the Compatibility issue always exist. During updating of the existing systems, for the updating of old technology to new tech. version, it's not a textbook possibility, that, always the success is achieved, at first stage, itself. ?? % updating, of the Communication is rarely achieved, at the first updating process itself. The updating of Communication system is not an one time step, but is a Continuous process. If the update is not completed, as planned the whole system collapses It's better, to take update back. It's always, the 'Trial- Error' mode of updating. If the update delivers the wrong results, it's better to getbàck to pre-stage. And, the matter must be throughly analysed, and suitable actions must be taken.

Para restaurar a conectividade da rede corporativa após uma atualiza??o crítica que a deixou inativa, é importante seguir alguns procedimentos de revis?o para identificar e corrigir possíveis problemas. Aqui est?o algumas etapas que podem ajudar nesse processo: 1. **Análise da Atualiza??o Crítica:** Verifique em detalhes qual foi a atualiza??o crítica realizada e quais foram as altera??es feitas no sistema. Compreender o que foi modificado pode auxiliar na identifica??o do problema de conectividade. 2. **Verifica??o da Configura??o de Rede:** Analise as configura??es de rede dos vários sites afetados para garantir que estejam corretas e consistentes. Verifique se n?o houve altera??es inesperadas que estejam impedindo a conex?o.

Une chose vraiment utile pour les maintenance est de tenir un mode opératoire où les impacts de la maintenance sont clairement indiqué, ainsi q’une procédure de retour en arrière détaillée avec même les connexions physique à remette dans leur position d’origine le cas échéant.

Check Update Documentation: Review the update release notes and rollback procedures provided by the vendor. Perform a Rollback: If the update can be safely reverted, follow the documented steps to rollback to the previous version. Ensure you have backups and restore points ready. Test After Rollback: Validate the network functionality by performing connectivity tests and ensuring all services are operational.

Para restaurar a conectividade da rede corporativa após uma atualiza??o crítica que a deixou inativa e considerando a possibilidade de restaurar backups, é importante seguir alguns passos específicos para garantir que o processo seja feito de forma eficaz. Aqui est?o algumas orienta??es: 1. **Identifica??o dos Backups Disponíveis:** Verifique quais backups est?o disponíveis para os vários sites da rede corporativa. Certifique-se de ter acesso aos backups mais recentes e completos, que possam ser utilizados para restaurar as configura??es e dados necessários. 2. **Análise dos Dados nos Backups:** Antes de iniciar a restaura??o, analise os dados contidos nos backups para garantir que estejam íntegros e atualizados. Verifique se os backups.

If available, use backup systems to restore connectivity quickly. Many organizations have redundant systems or failover mechanisms in place for such emergencies. Activate these backups to maintain operations while you address the primary system's issues. Ensure that your backups are up-to-date and properly configured to take over seamlessly. This approach minimizes downtime and allows your team to focus on resolving the core issue without impacting your network’s overall functionality.

I immediately contact vendor support when problems arise that are beyond my expertise or control - especially those related to my own hardware or software. Their expertise can provide valuable insights and solutions. Whether it's expert advice or patches, their help can help you troubleshoot issues caused by updates. I am confident that I have the important information - device models, software versions and protocols - ready to work effectively with the vendor. This also frees up internal resources to work on comms plans or rollback plans if needed.

Quando a rede corporativa fica inativa devido a uma atualiza??o crítica, uma op??o importante a considerar é buscar suporte junto ao fornecedor dos equipamentos ou softwares afetados. O suporte técnico do fornecedor pode oferecer expertise especializada para ajudar a resolver problemas específicos relacionados à atualiza??o ou às configura??es da rede. Aqui est?o algumas etapas que você pode seguir ao contatar o suporte ao fornecedor: 1. **Identifique o Problema Específico:** Antes de entrar em contato com o suporte do fornecedor, é útil identificar e descrever claramente o problema específico que está afetando a conectividade dos vários sites da rede corporativa após a atualiza??o crítica. Forne?a informa??es detalhadas sobre os sintomas.

whether it's a restore from backup, or vendor support repair, validating network functionality is critical. Start internal tests and at the same time ensure connectivity between site devices. Ensure that local services such as file sharing and printing are running smoothly. Next, go for cross-site links and ensure effective communication across all sites. Only after extensive testing and successful validation should the network be considered fully operational. Clear communication with stakeholders throughout the process is essential.

In the Whole process of restoring the failed system, the most important part is 'Testing Commissioning' of the system. Also, the testing procedure must not be diluted, at all. The help of specialized personal, who are the experts of the field may be taken, if necessary. The costs being paid to these experts, is immaterial. It must be restoration of ??%. No doubt at all. It's the duty of the restoring team to Completely making sure that the whole system is okay, and the bad story of failing is not repeated again. And, the whole process must be recorded, and the records are kept in safe custody for future reference. The Costs incurred, in the whole process must be analysed, & the responsibility must be accounted, and recovered if reqd.

It's always a good idea to use safe deployment practices to deploy updates and changes in phases. This is because it's easy to isolate issues when the scope is limited. Also,remember to stay as calm as possible. You're the right person to fix this.

In the Whole process of restoring the failed system, the vital factor of restoration and making sure that the mistake of loss to the Corporate company and cusomers, must be recorded, and analysed, as an Expenditure, whoch shpukd have been avoided, as an one. After completing the analysing, The Costs incurred, the whole process must be analysed, & the responsibility must be accounted, and if any human part is involved like any human error, from internal sabotage or external competitors/threats. They must be taken to task, and any penalty or punishment must be applied. Such that the bad story of failing is not repeated again. May Gpd the almighty bless all and everything to be okay, always.
