Thanks for the link Paul, have already gone over this. Although as author says, not very scientific, interesting anyway.

Will keep community posted about CDN progress on CDN idea:
http://feedback.cloudways.com/forums/203824-service-improvement/suggestions/6040498-offer-cdn-services-as-an-add-on

We have already started with it but waiting for MaxCDN people to implement some changes before offering it as an add-on.

Cloudways Team

Good read over here:
https://thethemefoundry.com/blog/why-we-dont-use-a-cdn-spdy-ssl/

Very much looking forward to your integrated CDN solution.
(turns out AWS CloudFront doesn't yet support SPDY https://forums.aws.amazon.com/thread.jspa?messageID=614324#614324 )

Yes, absolutely. SPDY capability only makes sense (and will kick in) when communicating over port 443 (https).

Cloudways Team

But doesn't SPDY require an SSL certificate?

Oscar, yes cloned applications will get the SPDY configuration too. So all but already existing applications as of yesterday.

Paul, we don't have set plans yet for HTTP2. Most probably will start looking into it next sprint (May). In any case, have created a separate entry in feedback page for HTTP2.

Cloudways Team

New, does that mean when an app is cloned or only when created from scratch?

Is it too early to ask approximately when you'll support HTTP/2?

All new deployed applications are being deployed with SPDY on. We will be evaluating impact and then deciding what do we do with existing sites.

Cloudways Team

HTTP/2 will be next.

Meanwhile, handy add-on for Firefox

and extension for Chrome
https://chrome.google.com/webstore/detail/http2-and-spdy-indicator/mpbpobfflnpcgagjijhmgnchggcjblin?hl=en

which both seem to work, pictured in each browser on Windows 10 below:

Good news!
On March 31st 2015 (yesterday), Cloudways enabled SPDY on my Nginx instance for my HTTPS site:
https://spdycheck.org/#tinkertry.com
Thank you, Cloudways!

Anybody else out there?

Looking forward to it, and glad I finished cutting over to https now. Cleaning up the side-effects was a bit painful, but now I'm one step closer to ready for HTTP/2.

As said, our focus will be on HTTP/2: http://arstechnica.com/information-technology/2015/02/http2-finished-coming-to-browsers-within-weeks/

Cloudways Team

it's nothing to test on really, it's all over the internet, you can check all speed optimization experts around the world.
most authoritative https sites have implemented spdy since a very long time.

SPDY will be going in a year or so:
http://blog.chromium.org/2015/02/hello-http2-goodbye-spdy-http-is_9.html?m=1

Most probably we will focus already in upcoming technology.

Cloudways Team

Yes SPDY is not magic, its already ''standard'' ... php5.5 or 5.6, MariaDB are not magic too, but all together its step forward.
In speed how technologies goes, this is not something new, its already implemented by many companies. I have hopes, that Cloudways will push progressive technologies faster instead of waiting somewhere back and just follow others.

When we get into this, we will surely measure performance impact for real world sites (like we are doing with MariaDB ...) and then decide.

Agree magic is difficult to come by.

Cloudways Team

It's not that magic : http://www.guypo.com/not-as-spdy-as-you-thought/

it's not even a matter of taste. SPDY is pretty much mandatory at this point for https optimization.
