Weird that only some worksites don't work.. it's a bit how a friend living over in China describes it - randomly some stuff is blocked. I hope we are not there yet..
Yes, well, I had an issue with getting to the Billion website in AU ... the ISP claimed no block, Billion claimed no block -- I got a temporary extra block of IPs to test and another IP was fine from the same ISP, but they never did find out what was blocking my normal IP, not the ISP, nor Billion. In the end I just routed the connection via another service, but most people don't have multiple services to /choose/ from. MTU can be an issue, maybe 1492 is too high for those sites. Try pinging with different byte counts and see if you can get through with lesser values, then adjust the MTU down accordingly if it helps. It would be /good/ if ping was a reliable testing tool, it is normally, but some people think that blocking ping makes them invisible on the net ... or their equipment supplier has that as the default.
