​Actually, I had a conversation a couple months ago with Doug Suttles at
Ookla.  He said they were interested/willing to add a bufferbloat test.

That's what spurred writing the document: to make their job easier; I
promised Doug on that phone call to write such a document.

Now we'll see if he follows through.

Note that some ISP's are actively interested in getting bufferbloat fixed
(e.g. Comcast, just look at Jason Livingood's recent tweets).  Bufferbloat
is between ISP's and the ability to provide better low latency services,
and some ISP's are wise enough to understand that.

So I don't think it's quite the situation that it appears on the surface.

​I'm very happy to see DSLreport's test indeed.  I hope it encourages the
other testing services to follow through.

​If you have contacts at those services, please send them a link to the
document.​

​Yup.
