When I just came to login, I got a page saying the server is down to try again later.
I pressed refresh 1 second later, and it loaded fine.
Maybe have been something along the route rather than the forum.
Update -
I know it doesn't solve for you Jocklad, but I have just posted 1 hyperlink and it works ok at this time.
It may be worth trying to post 1 now, so you can determine if it is a constant issue or an intermittent one etc.
