Ok, my bad
In 24-36 hours, the problems with the quotes website should be resolved. I thought it was Comcast’s problem, but before I called them, I took a look at my Network Solutions registry and ended up finding the real problem. The primary DNS server for the morlok.net domain was dns.morlok.net (70.89.203.89) but the 2nd and 3rd servers were set to gofast. Those remaining entries must not have been transitioned when I setup my own DNS hosting. Anyway, corrected the entries so that only my primary DNS server and my secondary DNS server (dns2.morlok.net — 70.89.203.90) are listed. For whatever reason, people on Comcast must have been having problems getting to the primary DNS server, and then they would have been sent to the backup. Or else there was some sort of situation when a Comcast DNS was caching things from when it couldn’t reach the server (perhaps due to the recent internet outage on my parent’s house) and that was causing the problem. Anyway, after the DNS cache clears itself, the problem should be resolved.
