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. -M<

Usually 5 to 7% CPU now 72% On usual Black Tuesdays though, there is quite a rush as well. Thing is this patch is alone while then there are a few. I believe it might even itself out in statistics.

Microsoft has used several CDNs in addition to its own servers to distribute the load in the past. Most organizations use from one to quite a few of their own distribution points. It would be interesting to know what the stats are at broadband providers... Although proxying may make the results a bit "nicer" in some places. Gadi.
net-op: traffic loads as the result of patching
So, maybe an operational question. What are people seeing as far as network traffic loads due to WMF patching activity, e.g. auto-update and manual downloads? Microsoft has used several CDNs in addition to its own servers to distribute the load in the past.
