This sound fine to me. I personally like the model where you pin to a
specific mirror, perhaps one that is geographically closer to your
datacenter. This also makes Squid caching (in the rack) happier in some

Thinking about how we might catch these ahead of time with our limited
resources ATM. These sorts of failures all seem related to configuration
and or requirements changes. I wonder if we were to selectively
(automatically) run check experimental jobs on all reviews with
associated tickets which have either doc changes or modify
requirements.txt. Probably a bit of work to pull this off but if we had
a report containing these results "coming down the pike" we might be
able to catch them ahead of time.
