Network Solutions' website and some of its DNS services were knocked out for around two hours on Tuesday, 4 April because of an outage involving its co-location provider, Savvis. The exact cause of the outage between 07:56 EST and 10:02 EST remains unclear.

Services have largely been restored, and Network Solutions apoligised for any inconvenience caused. The domain registrar is due to go over events with Savvis in a post-mortem designed to make lessons away from the incident, it said.

A spokeswoman for the firm explained that the outage impacted customer access to systems. "Services have been restored but customers may still experience some latency in receiving emails," she said.

Hackers have launched distributed denial of service attacks against Network Solutions' DNS servers last week in what is reckoned to be an unrelated incident. ®
