For me, since I joined, RAF has occasionally had trouble loading a page or ate a post or whatever, but I haven't really thought twice about it until the last week or so. What seems to be happening consistently to me throughout the work day (c. 8-5 MST) is that I can post or load 3 or 4 pages quickly like normal, and then the forum hangs up and refuses to load anything for 20 minutes or more, at which point it will load any RAF tabs I have open all at once. Once it's loaded everything, I can again post 3 or 4 times before it hangs again. I've noticed this on two different computers from three separate internet connections. Granted, they've all been on Firefox (I don't want to have to use IE or whatever for RAF... blech...), but it's not something I've noticed with any other website.
I did try logging in last night (about 12:30 to 1:00 MST) and the forum felt significantly less laggy than it has been. I did give up on posting, however, after several (5?) of my posts failed to actually... like... post. 5 in a row is worse than ever before. There's definitely something screwy going on here.
