My ISP?

Different times of the day and also varing lengths of time I recieve the message error server unavailable please try refresh etc etc.

This happens at any time from refreshing a forum, adding a comment to a thread or starting a new thread.

Only way I have found to cure is reset my router, simply power down and power back up and hey presto all fine again.

Lousy DNS servers maybe? Try pointing your DNS servers to somewhere more reliable.
