[ANNOUNCEMENT] [PLANNED] mysql1 upgrade

This Thursday, March 13, 2025 at 8:30:00 am EDT (see here for that time in other time zones). The host mysql1.int.ibiblio.org will be taken down for maintenance for a period of up to three hours. The end time of the maintenance will be 12:30pm EDT (link with info for other time zones).

During this maintenance window, sites running software such as wordpress, phpBB, or mediawiki will show database errors unless collection maintainers enable a maintenance mode appropriate to their software.

The specific errors will vary, but can include errors such as:

“Error Establishing a Database Connection”

503 Service Unavailable

“Database server is down”

If you see such an error for your collection during this maintenance window, and you know your collection uses mysql1 as its database host, this is why. Regardless of whether your collection uses this host, know that ibiblio staff are working diligently to reduce the number and frequency of unplanned outages, and to minimize the impact of planned outages such as this one.

We were able to complete this maintenance early. Sites that depend on mysql1 should now be fully functional. If you believe something is wrong with your collection that depends on mysql1, please do send us a message.
