Cannot load the forum at all

I’m posting on behalf of my friend Angel 666 > http://forums.shoryuken.com/profile/Angel%20666

For about 20 days now he hasn’t been able to load up the forum at all. Doesn’t seem to be banned. He tried clearing cookies, using chrome stealth navigation, switching up browsers - the forum just refuses to load for him. The rest of the shoryuken.com website loads just fine.
The extremely weird part is that I could access the forum with my phone on his wifi, so it shouldn’t be related to his router.
He can sorta load the forum using a proxy but it’s extremely dodgy and many functions don’t work properly (so he can’t try to log in that way, the form doesn’t work).
Any suggestion would be appreciated; I would PM a mod directly but there isn’t an index and so I don’t know who to write to.
Thanks
