I've also seen a few 25/110/111 requests in my logs 
but it didn't seem higher than 'normal.'

Best regards,

One thing that I see remaining since this past weekend is 
massive timeouts and latencies in mail delivery to very 
popular addresses (@hotmail, @rr.com, and @earthlink)  
@att.net seems to be accepting email without any major 
issues, hopefully all these issues will continue to slowly 
return to normal.

A single point of consumer data. I haven't checked by home 
router logs 
since Monday night but I was seeing a pattern of 
significant incoming 
port 80 traffic (I'm not running any services) over the 
last week or 
so, similar to increased 1433/1434 traffic before Saturday's flurry.

Best regards,

According to Matrix Systems 
(http://average.miq.net/Weekly/markR.html)
there have been two additional dropouts of global Web
reachability on January 26 and January 28.  These dropouts
have been for few hours or so, but nearly as large as we saw
from the SQL worm.  However it doesn't seem to affect other
network services, as measured by Matrix.  Just the measured
web servers.  The most recent was tonight from 3-5pm and
again from 5-7pm EST (http://average.miq.net/)

Any ideas what is causing them?  Measurement artifact?  Are you 
seeing something strange on your networks about that time?
