HTTP/2 support for all sites (completed)

Update June 13, 2018: This is complete, and HTTP/2 is now used on all websites we host.

We’ve updated the Apache web server software we use from version 2.4.25 to 2.4.33, which allows us to add support for the newer HTTP/2 protocol.

HTTP/2 is enabled for our own sites and a small number of our customer sites now, and we’ll be gradually rolling out this feature to all sites over the next few weeks. (We’ll update this post when that’s completely finished.)

Customers should not see any problems or downtime. We’re mentioning it here just so that customers who do notice a change for some reason will know about it. As always, don’t hesitate to contact us if you have any trouble.

What is HTTP/2?

HTTP/2 is a technical improvement in the way that web pages are delivered from a server to a web browser. The main advantage is that it can make complex pages load more quickly. The more complex a page is, particularly in terms of loading many different JavaScript and CSS resources (which many WordPress sites do), the better the performance increase.

All modern web browsers can use HTTP/2, but web servers need changes to offer it. We’ve been working on and testing the necessary changes for a while behind the scenes, and now we’re ready to offer it to all our customers.
