Getting logged out

 Both DW and LJ seem to be logging me out a lot at present. Is it just me, or is this hitting other people as well.

When I tried to log back on to the LJ, it told me my IP address had been temporarily banned.

LJ Log ins, or lack thereof...

 And it gets even odder. On LJ, I cant reply to a response in my journal.

I appear to be logged in until I try to reply. Then it tells me I'm not logged in, then it tells me to prove I'm  a human being, but with no box to follow instructions in....
