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.

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.

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?

Another 16" or so of snow from this blizzard, on top of the previous storms. I can't remember another winter with two blizzards. Even with the tractor and snow blower, it took two hours to clear the driveway.

Our back deck is amazing. You can see the umbrella poking its way above the patio table on the deck.  It's still very windy.

And now for the deep freeze....

With the increasing rate of melting of Greenland's icecap, I fear for Europe's climate.

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.

Just a couple inches of snow today.  Tonight we're in the deep freeze. The next storm starts Saturday; for the first time, it sounds like it will start as snow and end as rain (maybe 1.5"), and then we'll go back in the freezer.  Gloppy snow is by far the hardest to snowblow.

But while teaching my son to use the snow blower this morning, the blower didn't sound right and it became clear the drive chain was shot.   The first trip to John Deere resulted in a too small drive chain, so it was back to JD again. Only problem is the JD dealer is 35 minutes drive away.  So I got to spend the day being snow blower repairman.

Oh, and there is another picture of my back deck from a different angle to ogle at...

My weapon against the storm...  My old John Deer 455 diesel lawn tractor with 47" snow blower. So far, my guess is 26" (66cm) of snow down here (on top of a couple inches from the last storm).  Still snowing moderately, and 17F and windy.  It will be interesting to see what the final totals end up being by the time it's all over.
