Cloudflare’s view of the Rogers Communications outage in Canada

On July 8, 2022, an outage occurred at Rogers Communications, one of Canada's largest ISPs, impacting businesses and consumers. The incident began around 08:45 UTC and lasted for over 17 hours. Cloudflare data revealed a significant spike in Border Gateway Protocol (BGP) updates after 08:15, reaching its peak at 08:45. This suggests that the outage was likely due to an internal error rather than a cyber attack. The incident resulted in a near complete loss of traffic from Rogers ASN, AS812. As of July 9, 2022, at around 01:00 UTC, internet traffic started to come back gradually.
