I agree this is a local problem

Here is what i found so far

a) problem exists in
- ubuntu/firefox
- ubuntu/ephiphnay
- xp / firefox
- xp / chrome

b) problem doest exist or is reduced for
- ubuntu/opera

c) wget http://c.tile.openstreetmap.org/8/145/78.png succeeds in 0.07 seconds


wierd huh

I think c) and similar tests means there is no firewall problem

in ubuntu/firefox the following had no effect

mv /home/me/.mozilla /home/me/.mozillabackup

oh well 
my current workaround is use opera for all OSM stuff
