Sounds more like a local problem on your end, or issues between you and the CloudFlare facility you're being routed to. login.authorize.net. is a CNAME, but does not have any A records itself. login.authorize.net.cdn.cloudflare.net. points to two A records. > > Sometimes I'll get two A records which do work instead of the CNAME, > so login.authorize.net occasionally works if I get lucky. But the TTL > is 300 seconds to that luck doesn't last too long. There seems to be no issues on locations some locations across European countries such as e.g. Denmark, Germany, Netherlands, France and (ex-European) United Kingdom. CloudFlare does have the *SILLY* low 300 seconds TTL on ALL RECORDS that are proxied through them (and cannot be changed for those). Even on proxied records that have been the same for like 7 years, and easily could have been 86400, or even longer (although longer might be ignored by some resolvers). :'( -- Med venlig hilsen / Kind regards, Arne Jensen
