Customers of Rogers Wireless experienced widespread, hours-long outages of the company's voice cellphone service Wednesday evening, with gradual improvements as the night wore on but no indications of when the disruption will be fully fixed.
The countrywide problems are also plaguing Rogers's Fido and Chatr wireless brands.
The company first confirmed on its Twitter feed at 6:40 p.m. ET that it was experiencing "voice service interruptions affecting wireless customers in Ontario & Quebec," but later updated to say the outages were across Canada.
Posters on Twitter from Halifax to Vancouver said they had no voice service, and many also reported issues with text messages, or SMS.
At about 10:45 p.m., Rogers tweeted that its personnel "are investigating the root cause and services are gradually resuming."
"At this time we do not have an estimate as to when full service will be restored," the company said.
Data services such as mobile apps and web browsing appeared to be operating.
The main Rogers.com website was also down at around 7 o'clock and was still not loading at 8:30 p.m. It was working by 11:30.
The Rogers toll-free help line said the company was experiencing unusually high call volumes.
Police in Toronto warned residents about the problems in case they had an emergency and had to call 911.
The City of Calgary advised Rogers and Fido customers who need to reach emergency services that if they don't have a land line, they should ask to use the phone of a neighbour or a store in their area.
