Grrr.... Telemarketers no longer even do us the courtesy of a "live person"....

Phone rings.  I answer: "Hello".
Phone replies, with clearly an automated voice: "Hello, this is Ray".
I don't say anything.
Phone says: "Are you there?"
I don't say anything for a couple seconds.
Phone hangs up.

Unfortunately, browser only based tools can't tell you where the #bufferbloat  is, but at least it will tell you which direction, and how much you are suffering at any given moment.

Note that dslreports tool can be used on any kind of Internet service.

I had forgotten how wonderful the RITE project's video was and had forgotten to send kudo's in public. (I remembered to do so in private).
So those of you (which is most of you) suffering from #bufferbloat  and other bad performance who need to educate the general public about it should watch their wonderful video.  And then go do your part to fix the problems!
  RITE has, since its start nearly two years ago, worked to reduce the delay experienced when using the Internet. The approach is to make small, smart, changes to the mechanisms that makes Int...

This is wonderful work worth supporting.  The quality of the images and science it enables is amazing; that the Lunar Orbiter program was able to take such images in the 1960's is astounding.  There have already been research to determining the rate of meteor impact, and the images are the first that gives a baseline on the Earth's polar caps.
The LOIRP Project's goal is to complete the publication of the historic Lunar Orbiter Images | Crowdfunding is a democratic way to support the fundraising needs of your community. Make a contribution today!

Hiding from problems does not make them go away.
 
I lost my temper this morning. I would appreciate everyone here that cares about #bufferbloat to create an account and pile on virgin media after checking out my blog post http://the-edge.blogspot.com/2015/03/virgin-media-fixing-epidemic-of.html

I did my best to keep it civil, but of late, it has become hard to keep the venom back. Please see if you can be more constructive and do better.

Please also reshare, and amplify as best you can.
To whom it may concern at Virgin Media: My IP address is apparently now banned from accessing your site at all, for "advertising", on this thread about bufferbloat... and my post, was deleted. For the record, that url was: ...

This might have accidental relevance. Is there a security aspect to bufferbloat?

This is so true, though I believe there are other solutions. Once I was a window system expert; now, my answer is I'm not and others are experts. Once I was an HTTP expert; now, don't ask me for my opinion of where it is, and so on. Experts should reinvent themselves periodically, and never stay the expert for too long.... Life is more fun that way, anyway.
 
Food for thought, especially for all us who are experts in their field...

Yup, on Windows PingPlotter is a good tool; but as I don't run Windows, I had mostly forgotten about it.  As I remember, it has a decent graphical display, rather than mtr's text only tables of numbers you have to interpret.

And this is something you can do today on your Ubuntu system; add a one line long file to your system.  Please do so... You'll like it.

+Philipp Kern The best bufferbloat tool is netperf_wrapper.

In short, anything that saturates the link will do, however.  I did most of my early testing just using scp and ping (at the same time) to a machine I have at MIT.  You can even see the problem by running speedtest.net, and running ping at the same time as the test.
The big problem with speedtest.net is just that it doesn't run ping at the same time as it saturates the link.

Had my duct work in my house sealed yesterday via Aeroseal: I had suspected much of my energy bill might be going up in smoke, given the snow melting patterns on my roof, but I had no idea... One zone of the heating system, the one that has been operating the most, was losing just over 50% of the heat to leaks in the ducts. It will be interesting to see what my energy bills do now.

I won a very dubious honor: setting the record for leakiest duct work in a heating system for the contractor, along with running them out of sealing solution, which they had never had happen before.  The company that did the work is the one on this ATOH episode, Boucher Energy Systems.

In any case, one blow for my pocket book, and against global warming, and I hope my kids will find their rooms more comfortable.

In creating the weekend's controversy over #bufferbloat at virgin media - this song was stuck in my head:

https://www.youtube.com/watch?v=X2XCr2HJU1o

I have seen this musical ("Matilda") 3 times now, in london. This scene is one of the best... (you have to see it, just reading the lyrics doesn't give you the full benefit) and I have such massive amounts of empathy for the main character, who is a shy, smart, horribly oppressed young girl that "reads too much".... I cry every time at multiple scenes... The musical is WAY better than the book.
