smtp.xtra.co.nz --- sick?

I'm seeing funnies to smtp.xtra.co.nz --- basically some connections when sending email are terribly slow, while others work perfectly well. Does anyone know if this address is a load-balancer or something? If that's the case then it might be a host behind it is a bit sick or something... I'm seeing 10 second delays or more between having received a TCP ACK and getting an SMTP ACK back. The helpdesk didn't seem too interested, I didn't even ask if they wanted to see my packet dumps[1] :) --cw [1] Another outstanding pickup line. --------- To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog
