I have mentioned this B4 and dont understand why, but...
I dont think its always a BK issue or a ISP issue. 
I have trouble sometimes with BK (not at all this last 2 weeks as others have complained about which is weird)  but I only have trouble on my desktop PC.  I can boot up my laptop and NEVER have an issue with BK.   I dont know why, its very strange.

Sometimes I will be on my laptop playing here and the wife gets on the desktop and cant log on BK (strange? I think so)   So I dont think its always a BK issue or ISP.   So is it my PC?   Hmmm  well, that means lots of us have the same issue with our PCs (whatever it is  LOL)   But, like I said, how come I never ever have a problem when using my laptop?    If its a BK or ISP issue, I shouldnt be able to get on here like most everyone else.
