Kretch looked into it for me this morning, and this was his analysis:

and the heavy usage "square wave" in the top graph at that URL does
correspond to when machines would've been updating, so I'm guessing the
update was beating the repeater senseless.
Since a check with athinfo indicates some reasonable number of
Suns in w20 didn't finish updating until around noon today, I'm going to
start the Linux update process earlier tonight to compensate.
