@LWChris: If "it has failed to retrieve any updated data", could you explain how you found out?

The broken link seems to be an issue only in the UI but not in pulling the data? https://gerrit.wikimedia.org/r/#/c/operations/debs/wikistats/+/477961/

@Aklapper When I look at the List of largest MediaWikis, I see that at the moment, in the "Last checked" column, all entries have a timestamp between 2018-12-21 18:00:40 and 2018-12-22 05:50:32 and are highlighted as fetching (green). The three Wikias however have timestamps from 2018-11-07 respectively 2018-09-15 and are highlighted as broken (red).

Upon investigation on why this happens, I noticed that the links were displayed wrong.

I have to admit I assumed the table would be generated the other way round, i. e. the data source would be the raw links and all information for the table would be retrieved from that page. Apparently, the data is organized differently and needs some sanitizing. If you sort the table per timestamp ascending you see that typically a bunch of "Wikia" entries is in the front for all thresholds of "good". Usually, the Wikia does not exist anymore, i. e. has been deleted or renamed (redirects to another URL anyway), but for those entries that still exist, the link was the only reason I could see from the front end side.
