The telecommunications company stated in a press release that its service had been disrupted because of a “technical issue on the core network”, which it said was still being investigated.

Flow customers’ phones showed ‘No Service’ from late Saturday afternoon through Sunday.

“We sincerely apologize to our customers who were affected by this outage. We’ve launched a full investigation and will ensure that we take corrective measures,” said Paul Osborne, Flow’s country manager.

He added, “Our team worked through the night to get the services back up and running. While we strive to provide best in-class products and services, instances like these remind us that there will be challenges. Our commitment is to quickly resolve issues when they arise and get our customers back online in the shortest possible timeframe.”

According to Flow, its technical team was working alongside Ericsson Global Support to determine the root cause and continue to monitor the network.

Osborne also confirmed that a preliminary incident report has been submitted to the Utility Regulation and Competition Office (OfReg).
