The open CA prepares for ‘worst scenarios’ with new fiber, servers, cryptographic signing and more.
Let’s Encrypt just announced an infrastructure makeover which means the open certificate authority (CA) is able to re-issue up to 200 million certificates in a 24-hour period, something the service said could be necessary in “some of the worst scenarios.”
The upgrade comes a year after Let’s Encrypt was compromised by a Certificate Authority Authorization (CAA) bug and was forced to revoke 3 million Transport Layer Security (TLS) certificates on a single day, March 4, potentially leaving the sites behind them insecure or unavailable.
Let’s Encrypt, a free service of the Internet Security Research Group, has secured nearly 250 million websites, toward its goal of “100 percent HTTPS,” the group’s 2020 annual report said.
