Extension update of my wiki hosted on MyXWiki.org farm has also ended 
, see extension update check performed today …
This was expected actually, we had to reset the Solr index for the XWiki 15.0 upgrade (which was a bit more than 2 days before your message, but on myxwiki.org we trigger the Solr index for a specific wiki only when it’s accessed the first time and not when the main wiki is accessed) to fix a bug. See https://www.xwiki.org/xwiki/bin/view/ReleaseNotes/Data/XWiki/15.0/#HReinitializationofSolrsearchindexduringmigration for more details. Note that it will happen again for 15.1 upgrade (again because of a similar bug we missed in 15.0).
