Internet Black Holes
An anonymous reader writes "Hubble is a system that operates continuously to find persistent Internet black holes as they occur. Hubble has operated continuously since September 17, 2007. During that time, it identified 881,090 black holes and reachability problems. In the most recent quarter-hourly round, completed at 04:40 PDT, 04/09/2008, Hubble issued 46,846 traceroutes to 1,815 prefixes it identified as likely to be experiencing problems (of 78,772 total prefixes monitored by the system). Of these, it found 195 prefixes to be unreachable from all its vantage points and 139 to be reachable from some vantage points and not others." No relationship to that other Hubble which also tries to find black holes ;)
Wikipedia has more info on Black Holes in Networking ... and for grins, here is a

a large majority of them are in manhattan, followed by dc area, then france.

The world would be improved if those who think sophomoric mis-use of free speech is somehow funny fell into one.

this is so gonna hurt my Karma...

I thought the one with an interest in black holes was teh Hubbard :-)
It found a tonne of internet holes. Now what? Bhuler? Bhuler? Bhuler? Anyone? Anyone? Anyone?

Since traffic cannot go to these black holes, I don't think it matters. A white hole, constantly spewing out crap (spammer) is a real problem, but a dead machine doesn't matter.
Excuse me, but please get off my Pennisetum Clandestinum, eh!
The use of such extreme sophomoric speech in this context is often used in irony to mock those who use it seriously, thereby nullifying any real affect their stupidity may have on the rest of us. Please get off your high horse. :)
Can someone please explain to me what the purpose of this is? Seriously?
Since it's coming from University of Washington, presumably from a .edu domain, could these black holes simply be running PeerGuardian?
No, I think they're just being jerks rather than going for irony..
which is totally what she said
You mean circle-jerks.
Did anyone else find the map to be totally useless? It seems to me that the map more represents population density.

Further study has revealed that most of these black holes are caused by namespace collisions, such as overuse of the words "blackhole" and "hubble".
Sure does suck up a lot of peoples time....

Thanks to the RIAA, I buy them used...
1) The Large Hadron Collider is causing it.
2) The government(s) is capturing your traffic because it thinks your a terrorist, and it's losing packets due to the [Republican created] bureaucracy.
(a) And your packets are being water boarded
(b) AT&T helped
(c) The EFF wants to know
3) The RIAA is capturing your traffic because it thinks your a pirate, and doesn't know how to get them back to you at a reasonable price.
(a) Your packets are being sued
(b) Congress is helping
(c) The EFF still wants to know
4) It's a setup for the next Matrix movie. Neo's abilities are causing corruption in the matrix, creating failures in command nodes and putting millions of people to sleep. Like most of his movies.
5) The two Hubble's are tied together, and the internet is an existential manifestation of our physical universe as we discover it.
6) Global warming / El Nino's internet revenge.
7) Tubes are clogged.
I saw the site last night when it popped up on MetaFilter. For those of you who know, what are the differences between something like this and what shows up on the Internet Traffic Report?
If Nalgene water bottles are outlawed, only outlaws will have Nalgene water bottles.
They have a button where you can check if your current IP address is in a black hole. Anyone else find that ironic?

And here I thought this was going to be an article about 4chan.
i work at an isp and slapped in my mail server ip address.
this box has an uptime longer then they have been around and
its main path to the internet is an oc12 from mci.
the juniper that handles the oc12 has been up for years.
yet i had 90% reachability for every subnet i manage.
it makes me think their hosts may have had downtime and
how do they determine it? did any host have 100% reachability
in their testing? did they have one host with a terrible connection
not getting to the most places?
ah questions and no answers unless i want to dig into their website
in detail.
...because ANYONE who goes looking for this will have to sift through an impossibly high mound of totally unrelated "hubble space telescope black hole" stuff. Or WORSE, the former will start appearing in the middle of searches for the latter.
The same also goes for people who name their products or companies using simple short common terms strung together - whereupon a search for that returns a BAJILLION other unrelated hits.
This is sorta like "naming servers". "Short unique names that are easy to type." That's the primary criteria where I'm at. "Cute" and "in" and "cool" are completely secondary.

Hi, I'm Hubble, I'm looking for black holes!
That's Verizon (old GTE) network. The problem with this is that I use a 2ndary DNS server, 4.2.2.2, as a test to see if the Internet is "up". In about 10 years, if I have network connectivity, that address is pingable. And no, I've never been inside the Verizon network testing it... I've always been outside their network.
;)
So I don't see how it's only reachable %71 of the time from the Hubble project. Makes you wonder how many times the project itself is unreachable...
See we have this here new fangled linux based firewall (actually its pretty old) that simply ignores ping and traceroute requests...among others...who doesn't these days.
VSAT networks have known problems with ICMP, sometimes just long delay times that would cause a default packet to time out. I wonder how many firewalls/VSAT networks won't reply to all ICMP, thereby creating a "blackhole".
and secondly, who really cares if someone has their router turned off?
Last night while sitting in my chair
I pinged a host that wasn't there
It wasn't there again today
The host resolved to NSA.
I think you mean effect.

Please stop stalking me, bro.
Solution: Covertly, establish an bridge between our internet and the Intergalactic network. Make this bridge look like an ordinary internet user from the point of view of earth bound monitors.
Then you can sit quietly in the equivalent of your office and learn almost everything you need to know about events on Earth.
The people of Earth know nothing about this monitoring, because the bridge is concealed as the interconnect to regular earth internet users!
Logic and discernment should tell us that the interconnects should be located somewhere with in either AOL or EarthLink! If you want to hide a needle, you look for a large heystack!
It is commonly known that many AOL users seem to be not human.
The name Earthlink is a giveaway. Who would think to take this name literally? The purloined letter method.
Super Challenge to Earth Hackers:
Locate the interconnect, and hack it extracting data from the alien network!
The aliens have used this software many times before and have had eons to debug their security. The aliens use non-earth language that no one (except for coopted government personal) has seen it before. So you have an almost unsolvable problem in both hacking and translation. Earth governments have been coopted and will work against you, so you must keep your activities secret from all earth governments as well.
Good Luck.
Who divided by 0? :P

Fair argument, but I felt the Black Hole article brought back into scope.

A site that cannot be reached is about the opposite of a real black hole. A real black hole can be reached all too easily (relatively speaking), and the problem is it ain't so easy to leave.
What TFA is discussing is something more like "broken connection". Sorry it doesn't have the same resonance.
Most people don't even think inside the box.
