[Sysadmins] DNS issues

Been seeing a lot of DNS lookup errors in my mailserver logs for valid .ie
domains, and some .coms

Mailserver was slaved off "Irish Broadband" DNS servers at the data center,
which I changed to Google open access DNS, and the problem has largely
disappeared.

Been monitoring it, and got a repeat of the error for a single .ie that was
sending in mail.

Also noticed this week that the IEDR has been slower than usual on
actioning requests, could be totally unreleated.

Anybody else noticing DNS oddness lately?

Harry.
