911 emergency services in several states across the U.S. remain down after a massive outage at a CenturyLink data center.

The outage began after 12pm ET on Thursday, according to CenturyLink’s status page, and continues to cause disruption across 911 call centers. Some states have seen their services restored. CenturyLink has not said what caused the outage beyond an issue with a “network element,” but said in its latest update — around 11am ET on Friday — that the company said that it was “seeing good progress, but our service restoration work is not complete.”
