You can bypass DNS by using a hosts file pointing the hostnames to the right IP address. If you find no problem this way, then it's a DNS server issue (unless the machine u are testing has some other issues...but it would be unlikely) You can verify an ISPs own DNS by querying that server in particular (you can usually find their DNS servers in their support pages, or do dig ns [ISP_DOMAINNAME] the answers given may not be the NS used by end users, but should be close enough. If they have an old record in their cache, you should contact their DNS admin / NOC. good luck :) ( I know of one or 2 ISPs here in Oz that (used to?) fix the TTL of zones so they'd save in some traffic...of course, this made a mess of things). The problem may also be if the zones for the domains you are having problems with used to be hosted at those particular ISPs (eg, the ISP NS were the authoritative servers). If you then set other servers as the authoritative without asking the ISPs to clean up, their DNS servers will still be serving (wrongly) authoritative answers with old data. get in touch with them so they remove your zones from their servers.
