Czuch: But you have yet to address the reason Brainking seems to be so inconsistent between uses by the same user? Why are some days "normal" and other days with "problems"? Why is it different for Brainking than for other sites that all appear to be at least consistently good or poor?
The theory about problems in the connection between the user and the server is consistent with this symptoms - one hour you can be directed through a quick, less congestioned route; other times you can b routed through half way accross the world before getting to the destination. The internet can be very unstable sometimes...

All this recent talk about BrainKing.info just made me think about one thing though - if the problem is indeed in the route between the user and the server, then I guess people also have problems with the BrainKing.info site? I mean, the pages can be 2-4 times smaller than the regular BK.com pages but for the people complaining about the pages taking over 30sec to load I'm sure they'll notice some slowness too...
If, on the other hand, BK.info pages take only a couple of seconds to load, then other alternate theories should be considered...
And anyway, it's an alternative to test for people that say they don't know of other sites in Czech Republic to test from...

(For the record, I think that this is the most likelly theory... but it doesn't mean it shouldn't be proved somehow)
