A number of Rogers customers in southern Ontario who lost access to their wireless data and home Internet services Wednesday night were all back online by early Thursday.
A company representative reached by telephone told The Canadian Press that "everything has been restored ... everything is up and running" but did not comment on the nature of the problem.
Rogers had earlier acknowledged the problem on Twitter, saying it was working to resolve the issue as soon as possible.
Some customers in New Brunswick said their Rogers Internet services were down as well, although those outages weren't confirmed by the company.
While waiting for service to be restored, many customers took to social media to vent their frustration and the company was even trending on Twitter under the hashtag #rogers late Wednesday night.
"Internet is not working and #Rogers tech support lines aren't working .. nice ... how come their billing system never fails?" tweeted one man.
"A lot of productivity lost tonight from #Rogers outage. For the length of time, customers should see some compensation," said another.
Many affected by the outage had threatened to switch service providers, while others demanded compensation for the lost hours of online productivity. There were some, however, who saw the time offline as a welcome break.
"I got some reading in, played with the kitties, watched a DVD... almost sad my Internet came back on," tweeted one customer.
Rogers Communications identifies itself as Canada's largest provider of wireless voice and data services and one of country's top providers of cable TV, high speed Internet and phone services.
