The ISP's servers were unable to authenticate users who tried to log on to the Web on three separate occasions over the last few weeks, corporate affairs manager George Hazim said.
-It happened over a couple of days, for a couple of hours at a time. It wasn't constant," he said.
However, one iPrimus customer told ZDNet that one of the outages alone had lasted as long as three days.
Hazim could not say how many iPrimus customers were affected by the outage. Nor could he say which factors determined which customers were affected.
-It affected a fair portion of our customers, but not all," he said. -We moved quickly to fix it and it is fixed," he said. -It was an unfortunate thing that this happened."
iPrimus, the Internet arm of telecommunications company Primus, lays claim to a customer base of more than 200,000, making it Australia's fourth-largest ISP.
