Intermittent performance degradation and failures in South Brazil region – 12/15 – Mitigated


Final Update: Friday, December 15th 2017 23:40 UTC

We’ve confirmed that all systems are back to normal as of 19:40 UTC after the additional capacity has been added to our application tiers. During the incident, customers in South Brazil might have experienced degraded performance. We will continue to work with partners in Azure to fully understand the root cause.

Additionally, the previous attempt to update this blog around 21:00 UTC doesn't appear to have been successful which is the reason for the delay between the 'Next Update' time promised below and the current update. After the root cause of this incident is understood, we'll take a look at the logs of our communication tooling to understand what went wrong.

Sincerely,
Sri Harsha


Update: Friday, December 15th 2017 19:08 UTC

We continue to investigate issues with our South Brazil instance. Users may still notice intermittent errors. To alleviate impact, we have scaled out the application tiers and continue to stay engaged with Azure to understand root cause and other potential mitigation options.

Initial Update: Friday, December 15th 2017 17:48 UTC

We're investigating intermittent errors and performance degradation being noticed by accounts hosted in South Brazil. We suspect the issue could be with the underlying platform and we are engaging necessary teams in Azure to assist in investigation.

Users may notice intermittent errors and/or performance degradation accessing various VSTS features
