Fastly, which runs a content delivery network of servers and data centers, also said in a statement late Tuesday that it would work to prevent such a widespread failure in the future.
Although Fastly was able to get around the bug within an hour, it continues to deploy a permanent fix across its network. The company also said it is reviewing its processes and practices to determine why the bug wasn’t detected when it was introduced last month, and it will figure out how to get its network up faster if something like Tuesday’s outage were to happen again.
“This outage was broad and severe, and we’re truly sorry for the impact to our customers and everyone who relies on them,” Rockwell said.
Fastly helps improve load times for websites and provides other services to internet sites, apps and platforms — including a global server network designed to smooth out traffic overloads that can crash websites, such as a denial-of-service attack. The service accomplishes that by storing content and aspects of websites and apps on servers that are physically closer to the users trying to access a particular site or platform.
But because Fastly provides a layer of support between internet companies and customers trying to access the various online platforms it services, when it goes down, access to those platforms can be blocked entirely.
