Level 3 goes to Level 0 for American VoIP peeps

Network provider stumbles, drops voice traffic

Backbone carrier Level 3 says it is investigating the cause of an outage that took out its services in North America.

A spokesperson for the network provider told El Reg that the issue was resolved by 8:30am US Pacific time. The problems largely affected Level 3 VoIP and phone services in the East Coast and Midwest regions.

A heat map from monitoring site DownDetector showed the extent of the outage for much of the US and Canada:

The problems were also severe enough to impact the services of other phone carriers that rely on Level 3 interconnects to handle their traffic.

IT departments also reported issues with their VoIP systems.

The outage will be a nuisance for many, but the downtime can also have significant consequences for customers and operators alike. In 2015, the FCC handed out fines to CenturyLink and Sprint after it deemed their service outages were bad enough to warrant a public safety hazard.

While Level 3 services have since returned and customers are reporting their phone lines working again, the cause of the downtime is still unknown. El Reg will update if and when we get more information. ®

    Infrastructure operators are struggling to reduce the rate of IT outages despite improving technology and strong investment in this area.

    The Uptime Institute's 2022 Outage Analysis Report says that progress toward reducing downtime has been mixed. Investment in cloud technologies and distributed resiliency has helped to reduce the impact of site-level failures, for example, but has also added complexity. A growing number of incidents are being attributed to network, software or systems issues because of this intricacy.

    The authors make it clear that critical IT systems are far more reliable than they once were, thanks to many decades of improvement. However, data covering 2021 and 2022 indicates that unscheduled downtime is continuing at a rate that is not significantly reduced from previous years.

    'Network engineers walked over each other's changes'

    A large chunk of the web (including your own Vulture Central) fell off the internet this morning as content delivery network Cloudflare suffered a self-inflicted outage.

    The incident began at 0627 UTC (2327 Pacific Time) and it took until 0742 UTC (0042 Pacific) before the company managed to bring all its datacenters back online and verify they were working correctly. During this time a variety of sites and services relying on Cloudflare went dark while engineers frantically worked to undo the damage they had wrought short hours previously.

    "The outage," explained Cloudflare, "was caused by a change that was part of a long-running project to increase resilience in our busiest locations."

    The upstart, founded in 2018, claims this platform lets customers automatically stitch together multiple on-prem datacenters, branches, and cloud workloads at the press of a button.

    The subscription is the latest evolution of Alkira’s multi-cloud platform introduced back in 2020. The service integrates with all major public cloud providers – Amazon Web Services, Google Cloud, Microsoft Azure, and Oracle Cloud – and automates the provisioning and management of their network services.
