The good news is that I reported this particular site as a problem two and three years ago, both, and it isn't any worse.
did you contact Pay.gov Customer Service at: 800-624-1373 (Toll free, Option #2) or send an email to pay.gov.clev () clev frb org I just called, but I can't duplicate the problem and they need to work with someone that is having a problem reaching the site. Regards, Lee

They need to test from behind a 1280 mtu link. The DNSSEC testing is also insufficient. 9-11commission.gov shows green for example but if you use DNS COOKIES (which BIND 9.10.4 and BIND 9.11.0 do) then servers barf and return BADVERS and validation fails. QWEST you have been informed of this already. Why the hell should validating resolver have to work around the crap you guys are using? DO YOUR JOBS which is to use RFC COMPLIANT servers. You get PAID to do DNS because people think you are compentent to do the job. Evidence shows otherwise. https://ednscomp.isc.org/compliance/gov-full-report.html show thebrokenservers for .gov.

Most people don't have the skill set to force the use of IPv4. If it is production it should work. It is the I-G's role to ensurethishappens. Butts need to kicked.
