Greetings!
Over the next two weeks our network staff will be adjusting and restarting the eqiad network switches. This will affect every server and service running on WMCS, both toolforge and cloud-vps.
We don't expect this to result in noticeable downtime, but any connections that are active during the restarts will be interrupted. It's also always possible that some unexpected side-effect will result in a prolonged network outage.
One switch will be restarted at 15:00 UTC on July 20th, 22nd, 27th, 29th. The restart on the 27th is the most likely to affect cloud services.
To avoid worst-case scenarios the WMCS team will be failing over several services before the restarts. Most of these changes won't be noticeable to users but we'll notify in advance of impact if anything dramatic is expected.
