There will be a Maintenance Window for the Forum today July 27, 2023 for about 30 minutes.
During the window the Forum will be read only and at some point you may get a 404.
The start time is not yet determined (some time in the next few hours from the time of this post 2023-07-27T13:31:00Z ) but all work should be completed by 2023-07-28T00:00:00Z
Some browsers that are holding a connection to the old server/IP may still be seeing a “404 not found” message. Trying another browser or an incognito window until your browser decided to re-open the connection is a work-around.
