No, you're not alone. This lag spike issue has been around since the near beginnings of 1.10. Sometimes it happens constantly; Sometimes there will be days when it doesn't happen at all. Luck, I guess.
As for the forums, I haven't the slightest. Although, there were a number of related threads about it.
To quote a reply from one of those threads...

The forums have been buggy for the better part of the week. They were down most of the day for me, but overall they've been up even though a little messed up. So long as I can get my fix the bugginess isn't so bad. More of a headache for the mods than anyone else.
Speaking of which, sorry mods- I'm double posting all over the freaking place right now....
