The fact that it only affects some of Mozilla's CI while it seems it was
put in place in response to Mozilla's CI asking too much would indicate
the blocking is not efficient. Curiously, though, it seems there
shouldn't have been much activity from Mozilla's CI on the date shown in
that file (at least not large compared to some other days), so maybe it
wasn't in response to that, in which case we are collateral damage,
reinforcing the point made by Noah.
