Not seeing anything on bat's graphs anyway. I presume the nightly spike 
at 2am is updatedb or something similar.

Troublesome times that spring to mind are mid-afternoon of Dec 30th, and 
in the small hours of Dec 31st just after midnight (both of these seemed 
to last a couple of hours). There were other times too, but I don't have 
an accurate idea of when.

Around 01:30 on Dec 31st (iirc), I tried telnet www.openstreetmap.org 80 
and GET / HTTP/1.0, from different IPs in Ireland and the UK, to 
eliminate any question about my connectivity at home. Results varied 
from not getting a TCP connection, to taking a long time (over a minute) 
to answer the GET, to getting a connection but timing out after the GET 
was sent.
