We will be performing maintenance on the Cloud VPS network next Tuesday (2024-05-21) starting at around 14:00 UTC. During this window we will be replacing some software on the Cloud VPS network router.[0]

During the maintenance window there will be a brief period during which Cloud VPS and any services hosted there (including Toolforge and PAWS) will not have any external network connectivity. Based on tests done in our staging environment the full outage should last for less than a minute assuming there are no unexpected issues.

There is no action required on your side, unless your tools are not resilient to unexpected network outages - in that case you may need to manually restart those tools after the maintenance is complete.
