Next week we will start upgrading application servers (where all applications run) to the latest version of software and supported infrastructure. The upgrade will require servers to stop all applications and reboot multiple times.
We expect that average downtime will be:
- About 20-35 minutes for all non-AWS regions (Eastern Europe, Central Asia)
- About 10-15 minutes for AWS-based regions (all other regions)
In some cases deployment of new versions/new applications will be unavailable for up to 2 hours after the upgrade due to additional checks and post-upgrade finetuning.
The upgrade will not be applied to dedicated services (Business Dedicated and Enterprise customers). We will upgrade Enterprise customers servers on a case-by-case basis during upcoming scheduled maintenance windows only.
