I can't, and don't, speak for Sean, but I think he meant carrier side.
I didn't know WSUS was a local update server, but I do now. I think
in terms of Internet operations it's irrelevant how a WSUS is fairing
since that is completely under the control of the person operating it
i.e. get more memory, disk, or allocate more b/w if you have too ..
and it's that important. MS did the right thing and made it free after
all.
I cant see that anyone is seeing anything other than the "same o". MS
patches all the time and has a lot of experience in capacity management so I
would think that they would've said something if it was to be different
than other patches. I've been monitoring IX stats and I am not
seeing much including small anomalies. In one of the European IX's
I saw what looked like the botnet itself operating. There was a delta
on the patch release and the anomaly dropped, but I can't confirm it
was related to the worm. Speculation, but a fair one. I didn't contact
the IX since it dropped off and don't plan to. I think that this is just
another day on the Internet. Unfortunately.
