Probably a dupe of T370304. But that's (in my uninformed opinion) a chameleon task covering two unrelated issues so I don't want to close this as a dupe.

Down from unbreak to high - Site not actively having issues.

I am okay with being closed as dupe. It would be worth noticing here (and echoing in the other task) that the wikis involved where on two different server clusters (enwiki is on s1 and fawiki on s7). Shouldn't circuitbreaking issues only impact one server cluster?

In eswiki it happened on July 19 at 00:30 UTC around that time and from then on the error began to appear.
