Internet users had something of a rough ride over the weekend with both TelstraClear and Xtra experiencing outages.
Xtra's problems arose from a software upgrade on its IP.Net product range, according to Xtra marketing manager Chris Thompson.
"A software vendor was upgrading ports on IP.Net and that upgrade had to be backed out. During that time some customers with particular configurations - those running connection scripts - were affected."
At roughly the same time, Sunday morning, TelstraClear suffered an outage that it says affected only a handful of customers.
"I can confirm it was a problem with an X-12 network card that was fixed and that it affected around 40 customers," says spokesperson Adrienne Wilson. IDGNet understands Wilson is referring to an X-21 serial interface card.
Wilson was unable to confirm that domain name registrar Domainz was also affected. A posting to the network operators group (NZNOG) mailing list suggests that the domain name servers (DNS) were affected, although not knocked out entirely.
"As we have two-thirds of the NZ name servers reachable, there shouldn't have been any loss of service nor significant performance degradation in the NZ DNS," the posting said.
IDGNet contacted the domain name commissioner, but was referred to NZ Registry Services for comment on operational matters.
Registry manager Nick Griffin says the outage did knock out two DNS servers.
"There are seven DNS servers operating in various locations and on various networks both in and out of New Zealand. The outage did affect two of the DNS servers, that operate on the TelstraClear network, but most DNS queries come via caching name servers that are capable of recording which name servers aren't answering in good time."
Griffin says performance degradation was minimal.
