When I last had something to do at an ISP[1], we would regularly see our
Akamai deployment jump from 10-20Mbps at 8am on Wednesday morning[2], to
40-60Mbps by 9am for an hour or two, around Patch Tuesday.
We found it very noticeable then. I don't see it so noticeable on a
carrier network doing ~8Gbps with hundreds of K of subscribers, these days.

[2] NZ is some hours ahead of the US timed patch releases. 8am-9am is
when most people turned their PCs on in the morning, which then appeared
to commence downloading.
