Our support staff was in hell Monday and it continues this week because of DST.
Microsloth in their infinite wisdom decide to leave out the DST patch from SP3. Genius.
WSUS didn't push the update either.
We had phone issues, blackberry issues, VPN issues...
So YES the DST issue caused alot of issue and probably is an issue for your routers on the way to here.
Hope it all gets fixed in a jiff, won't be the same without our pals over 'yonder'...
