More than two billion OCSP lookups in a single day
Yesterday I wrote about recent research indicating that VeriSign SSL Certificates are used disproportionately more on larger and more established web sites. Supporting that information is today's announcement that on Monday (which by pure coincidence was VeriSign's fifteenth birthday), for the first time ever we managed more than two billion OCSP lookups in a single day. That's noteworthy in part because OCSP traffic has doubled in size in less than a year. Drivers of this growth include increased adoption of Extended Validation SSL and increased use of Code Signing certificates.
