Changed to OpenDNS and got right in. Completely unexpected - CenturyLink is my ISP... pretty much my only access where I am without paying beaucoup bucks for satellite (and 60GB/month before massive throttling/overage charges).
My guess is if they didn't block other more controversial stuff, it must be an automated process that blocked the IP pool catbox is in.
You might wanna shoot them an email and ask to whitelist that domain.
