Add query for pypi mirror infra bug 1334550

This has 327 hits in 7 days, multiple queues and jobs,
it's mostly failures but has a few hits on successful
jobs. I tried filtering success vs failure to see if there
was some obvious difference for the success hits but
couldn't find one, so risk-assuming that the low
success rate will stay low to avoid false-hits.
