Heartbleed causing internet congestion. All the SSL certificates being revoked is causing all the browsers to have to update their revocation list, causing massive download traffic at certificate authorities.
According to CloudFlare, GlobalSign’s CRL grew from 22KB before Heartbleed to 4.9MB afterward.
The number of revoked certificates on the CRL increased from 1,492 to 133,243. And that was just GlobalSign’s CRL.
The update to the CRL list caused a huge spike in requests from browsers for the latest list, which in turn caused a drain on GlobalSign’s bandwidth.
