Network maintenance will be happening on Tuesday, July 20th at around 1500 UTC that will affect the maps and scratch cluster on both nodes (see https://phabricator.wikimedia.org/T286069 https://phabricator.wikimedia.org/T286069). It should be extremely short in duration (measured in seconds, not minutes). Therefore, we will not be failing them over.

WMCS will keep an eye on the impact to client VMs and will remediate problems where necessary. If all goes well, most services won’t notice.
