Apache 2.4 web server upgrade (complete)
Update May 3, 2018: The change described below is complete on all servers.
Over the next few days, we’ll be updating the software used on each web server from the Apache 2.2 series to the 2.4 series.
Customers should not notice any changes or downtime. We’re mentioning it here just so that customers who do notice a change for some reason will know about it.
While the Apache 2.4 series has some changes and new features, we’ve intentionally kept things compatible with older versions. In particular, we’re using mod_access_compat to ensure that existing “Allow / Deny” authorization directives work, and we’re using SSILegacyExprParser on to ensure that existing Server Side Includes work.
The Apache 2.4 series brings changes we’re using to improve our customers’ websites. For example, we’re already using OCSP stapling to speed up the initial connection to SSL sites in many browsers, and in the future we’ll be adding support for the newer HTTP/2 protocol. Neither of these were possible with older versions of Apache.
As always, don’t hesitate to contact us if you have any trouble.
