Server support and usage
As of March 2012, there are not many SPDY-enabled websites. Some Google services (e.g. Google search, Gmail, and other SSL-enabled services) use SPDY when available.[26] Google's ads are also served from SPDY-enabled servers.[27]
Twitter has enabled SPDY on its servers in March 2012, making it the second largest site known to deploy SPDY.[28]
Cloudflare is also providing a beta of SPDY on their servers from June 2012, though users who would like to use/test it must be paying customers as SPDY is built on top of TLS, only paying customers can use SSL/TLS Certificates.[29]
In March 2012, the open source Jetty Web Server announced support for SPDY in version 7.6.2,[30] while other open source projects were working on implementing support for SPDY, like node.js,[31][32] Apache (mod_spdy),[33] curl,[34] and nginx.[35]
In April 2012 Google started providing SPDY packages for Apache servers which led some smaller websites to provide SPDY support.[36]
In May 2012 F5 Networks announced support for SPDY in its BIG-IP application delivery controllers.[37]
In June 2012 NGINX, Inc. announced support for SPDY in the open source web server Nginx.[38]
In July 2012 Facebook announced implementation plans for SPDY.[39]
In August 2012 Wordpress.com announced support for SPDY across all their hosted blogs.[40]
