Rogers Communications said on Saturday that it had restored service for most of the affected customers. Some customers may experience a delay in regaining full service as our services come back online and traffic volumes return to normal. It promised that it was working hard to get customers online again.

Rogers said in a letter that it was working to understand the root cause of the problem and that it would make changes to avoid a repeat. The company promised to give a bill credit to everyone who was affected by the outage.

Following our previous updates, we have now restored services for the vast majority of our customers and our technical teams are working hard to ensure that the remaining customers are back online as quickly as possible.

Rogers has yet to give a reason for its entire network to go down for a long time. The company believes that the incident is likely to be an internal error and not a cyber attack. The outage may have been caused by a Border Gateway Protocol issue. A routine BGP update went wrong and caused the massive outage that took down some of the internet's most popular sites.

The effect of the outage was obvious. People used their phones and computers in public libraries. Toronto Police noted that some people couldn't call for help due to the power failure. The Interac system, used by Canadian banks to connect their networks, was down, causing ATMs to not work. NetBlocks found that Canada's national internet connection dropped to 75% of normal levels. The episode is likely to reignite discussion about Rogers' dominance in the telecom market.

ℹ️ Update: Metrics show internet service is being gradually restored in #Canada after an outage at operator Rogers that knocked out a quarter of the country's observable connectivity.

The crippling incident has raised questions over the centralisation of critical infrastructure.
