Many major websites crashed Thursday afternoon after a major Internet service provider reported an issue with its internal systems.
The websites of a number of companies appeared to be affected, including Southwest and Delta airlines; financial giants Schwab, American Express, Chase, Discover and Fidelity; and home improvement retailers Home Depot and Lowe’s.
The cause appeared to be an issue with Akamai, a widely used Internet service company based in Massachusetts. Just after noon, the company posted on its site that it was struggling to resolve its domain name service, the Internet “phone book” that directs URLs to digital web addresses.
The issue was resolved just after 1 p.m. EST, the company said.
Akamai’s problem shows how fragile a consistent Internet service can be, where a setback in a large organization can translate into problems for millions of users. Previous Internet outages have also been attributed to problems at Akamai and other Internet service companies.
The company did not immediately respond to whether the outage could have been caused by a malicious actor, but DNS issues are common for internet connectivity companies.
Akamai said on Twitter he later “implemented a fix for this problem” and it looked like “the service was resuming normal operations,” but the company did not disclose any issues that may have caused the major outage.
“We will continue to monitor to ensure the impact has been fully mitigated,” the company added in a statement also shared by an Akamai spokesperson.
The spokesperson did not immediately respond when asked for further details on the cause of the outage and how the company could have addressed the issue.
