Nothing to do with my forum software.
The internet travels through hops, think of them as roads.
You can do a trace route from your computer to my forums and you will see each hop it hit to get to here. If any of those hops had a problem the last few days then you wouldnt have been able to get to the site while other users who comes in from a different path worked fine.
Nothing I can do when that happens, you just have to wait it out.
