Sasktel is still investigating what happened to knock out its internet service on Thursday.

The service was out for about an hour and a half, beginning at 6:00 PM Thursday.

The corporation's Michelle Englot says the outage was widespread. "It was pretty much all of our province-wide landline internet service, which also affected the WIFI services," said Englot. "So our wireless internet was still working." she added.

Englot says they need to figure out what caused the problem so they can make sure it doesn't happen again, but as Friday afternoon, the cause had not been determined.
