I think this slowdown started before the Net bill was signed. Unlike HBA, most websites respond quickly. Perhaps the net neutrality bill had a hidden rider called the aviation forum neutrality clause to help others compete against the ever popular (and vastly superior) HBA forum.
Feels like a DNS (Denial of Service Attack) issue, there are only 50 on line as I write this. I wrote to URLJet.com who may or may not be the host and they said (I think)(poor typing on their part) and (probably only one guy working the help today) it appeared that the site was overloaded. Your host I would think should help with this, maybe its time for a new server.
