Note from SRE Regarding the Swift Migration
On behalf of SRE,

As we have been mentioning for months, we are finally going to be beginning our file storage migration from our current software (GlusterFS) to a new, more modern software (Swift). GlusterFS is an outdated and inefficient technology. It has frequently caused issues with our MediaWiki performance, and some of the sporadic 503s can be attributed to it.

Swift is a much more modern storage software, which is used by the Wikimedia Foundation, and has better performance for the high volume of traffic. We have been working hard to get everything in order, and working with this new storage solution. There should hopefully not be to many user-facing interruptions during this migration, but you could at some points during it experience some issues. If you do, please let us know.

We have already started the migration by first switching over all new wiki creations to use Swift. Soon we will begin switching other wikis over. We will be doing it so that all wikis starting with the letter "a" will be switched over first, then once they are done, all wikis starting with the letter "b" will be switched over, and so on and so forth. We expect the total timeframe of the migration to last around one month before all wikis are switched over.

However, there is one unfortunate side-effect of this: during the migration, and potentially a little bit longer after the migration is done, we have to disable the ability for wikis to generate their own dumps using Special:DataDump. If you need to request a dump before we are able to get it working again, please request so on Phabricator.

 * AdvanceWarsWiki's images uploaded before 18:12 are showing up as errors. . The one I uploaded recently is ok though . OrangeStar (talk) 18:24, 28 October 2022 (UTC)
 * This issue is no longer happening, the first two images returned but the third got lost, I just decided to reupload the third and move on. The migration to swift looks like a success in that wiki, because I feel like the wiki's loading times are reduced notably, but still, it's a wiki that basically I edit and read only myself for now, we'll see how it goes in more famous wikis.

 * I apologise for the issues that occured earlier. The issue at that time was caused by a configuration change that has been fixed. Please let me know if you encounter any further issues. I will note however, that during this migration there may be times that a few images might not appear correctly. That is because they are still being copied over to Swift. It shouldn't be a highly common occurrence, but it may happen at some times. Perhaps for a few hours to maybe a day or so. Universal Omega (talk) 05:41, 29 October 2022 (UTC)
