We're going to be doing some upgrading and moving around of things related to wiki.postgresql.org tomorrow evening, July 2nd, European time. Due to the software it's running (mediawiki) we expect more than normal downtime and issues during this work, so please be prepared for this.
There should be no issues with changes to the wiki -- if it's up and accepting edits, you can expect those edits to remain after the service is completed. But if it's down or throwing errors on edits, just give it some time and try again later.
Work will commence around 17:00 UTC. We have no estimate at this point when during the work the downtime will be.
