See original failure: #158774 (comment)

I believe this has been a recurring issue, I remember one of @khyperia's PRs fell to it?

[jieyouxu]

I swear there was an ancient issue about this... but I don't remember which issue exactly
I mean there's #134220 but that's probably different

[Mark-Simulacrum]

#38878 is the ancient issue, we removed the retry loop mitigation for it a while back.

[workingjubilee]

Too optimistic, huh.
