OTTAWA -- Bell Canada and TELUS say service has been restored in Ottawa and eastern Ontario after "brief service disruptions" over the lunch hour.

Customers of Bell and TELUS reported widespread network outages with cellphones and internet service just after 12 p.m.  Several people, including CFRA's Kristy Cameron, reported Internet service returned after 1 p.m.

Bell Canada responded to complaints on Twitter that it was aware of the problems and technicians were working to fix the issue.

Residents of Renfrew County are being told to call 911 from landline phones due to an issue with telecommunications across eastern Ontario.

The County of Renfrew issued a media release saying "due to a widespread telecommunications failure, please advise all to use a landline to contact 911."
