One of them is a Class Action lawsuit filed by LPC Avocat Inc. As seen in the July 8 activity graph, there was a clear spike in BGP updates after 08:15, peaking at 08:45.Ī number of consumer and business lawsuits have already been filed against Rogers due to this network outage. Outage was said to be due to an update issue, which Cloudflare data confirms. For Rogers, it was the second major outage in just over a year. Customers flocked to cafes and public libraries to access alternative networks, while financial institutions reported problems with everything from ATM machines to cashless payment systems. The nationwide shutdown even affected banks and emergency services (some callers have had difficulty dialling 911). July 2022: Major Rogers outageĪnother major outage occurred to one of the largest ISPs in Canada, Rogers Communications, it happened on Jand affected both residential customers and businesses. According to Cloudflare, the failure began at 06:27 UTC, and by 07:42 UTC all data centres were online and working properly. This misconfiguration of the router prevented the correct IP routes from being advertised, thus preventing traffic from properly passing through to the Cloudflare infrastructure.Īlthough only 5% of Cloudflare's network was affected, the outage affected 50% of the total requests, delaying or denying access to the websites for millions of users worldwide, as can be seen in the Cloudflare outbound bandwidth graph:ĭespite a massive system outage, Cloudflare was able to quickly find the root cause and perform a service recovery procedure within a couple of hours. When running the update code, a network configuration code error affected the sequence of BGP (Border Gateway Protocol) network routing protocol advertisements, and a misconfiguration in the diff format changed the order of terms in the BGP list of prefixes, stopping the advertisement of network reachability information by itself, and hence removing access to the affected locations, which prevented servers all over the world from contacting the origin servers. The outage significantly impacted internet access for many apps that depend on it to deliver content to users around the world, including FTX, Shopify, Fitbit, Discord, Omegle, DoorDash, Crunchyroll, NordVPN, and Feedly.Īccording to Cloudflare's official post, this outage was caused by a change that was part of a long-term project to improve resiliency of the service in the busiest places (which is quite ironic). On June 21, 2022, Cloudflare experienced an outage that affected traffic in 19 data centres. Let's take a look at some of the other most notorious outages and downtimes this year. In 2022, a series of high-profile Internet outages further demonstrated our world's dependence on cloud and telecom service providers, as well as the fragility of an increasingly overburdened infrastructure. Lucky for us users, Facebook stated that “the root cause of this outage was a faulty configuration change” and that there is “no evidence that user data was compromised as a result” of the outage. The site Downdetector, which monitors network outages, recorded over 10 million problem reports. The leader of 2021 among global outages was undoubtedly the seven-hour shutdown of Meta services (Facebook, Instagram, WhatsApp), which occurred on October 4 and affected hundreds of millions of users in the company's corporate partner client base. Internet outages and blackouts do not only affect home users on the fixed networks, but they can occur on a much wider scale and impact mobile and traditional voice communications and even emergency call centres, causing severe problems for an entire region or country. However, larger and longer Internet outages are becoming more impactful and disturbing. The massive service outages are a stark and persistent reminder that big tech giants should keep the infrastructure firmly under control. Uptime Institute’s 2022 outage analysis finds that downtime costs and consequences are worsening, and that networking issues are among the main causes of IT outages. With increasing reliance on digital giants who deliver to us all cloud services, massive internet outages have become more frequent.
