Hi.
https://www.mediawiki.org/wiki/Gerrit/Reports stopped updating for a few days due to https://bugzilla.wikimedia.org/60940 as far as I can tell.
For now I've just disabled checking changes that have a status of "closed". The reports should resume updating daily, but some of the reports will likely be incomplete or inaccurate until this bug is fixed.
If anyone would like to take over the maintenance of these Gerrit reports, they're yours for the taking. I'll even throw in a free bot account. :-)
