Really strange... Only websites working at the moment from those I try (all rigs, all browsers) are SF, 8F, Google, Speedtest.net and a Finnish newspaper plus GUI's for our two IPTV services. All others time out: CNN, BBC, TechNet, German and Finnish news sites, WordPress, online banking etc.
Streaming IPTV television comes without problems, both from Finland and Germany but for instance YouTube and Vimeo do not work ATM. I am currently not able to watch videos from these sites, the sites do not open. After posting this I'm going to see if I can upload an explaining video to this post from my neighbors.
I have now tried over 40 sites I normally visit more or less regularly, five sites work, others don't. Seven Forums, Eight Forums, Google, Speedtest.net and Iltalehti.fi, a Finnish newspaper are working without problems but clicking an external link in any of these is a no go. Online banking is also not possible ATM.
Any ideas? Belkin N1 Vision router, very fast VDSL connection. MSE 2, Windows Firewall. Until yesterday evening no problems, since that no updates on computers or router. One of the working websites is Speedtest.net which gives totally normal ping and speed.
My neighbor has the same ISP, having no problems, so I used his connection to upload this to YouTube. It shows my problem better than I can describe:
