We are able to confirm that all services impacted by today’s IP outage have been restored. We understand how important these services are to our customers, and we sincerely apologize for the impact this outage caused.

Although we and their other global customers withdrew routes and shut down peering sessions, they continued to announce them to their peers regardless. This caused black holing of any inbound traffic routed via CenturyLink. All affected customers were left powerless and it has been a case of having to wait for them resolve the issue.

Thankfully less than 10% of our overall traffic routes in via CenturyLink's network, so the impact was minimal. We know of only a small handful of destinations that were unreachable during their outage. Apologies if your access was disrupted.
