Internet Black Holes

CmdrTaco posted more than 6 years ago | from the you-can't-get-there-from-here dept.

Networking 100

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 ;)

The Uncyclopedia has this to say about Black holes:

"Black holes are simply where I decided to divide by zero"
~ God on Black Holes

"That's crazy"
~ Mr. Replier on God's black holes

"It's a hole that is black"
~ Captain Obvious on Black Holes

"It's a hole that is white"
~ Captain Sarcasm on Black Holes

"Falling in is bad for your health"
~ Captain Understatement on Black Holes

"Originally, Black Holes were known as 'Gravaitationally Collapsed Stars'"
~ Steven Hawking on Gravaitationally Collapsed Stars

Oops, wrong black holes. We're discussing internet black holes, right? Wow, what a coincidence, when I went to the Uncyclopedia to look up black holes I see the featured article on its front page reads

So I was online, right, just chatting away with my friends about normal things. Porn, killing fluffy bunnies, the sad state of the world, things like that.

When all of a sudden --
Well, maybe it wasn't all that sudden, when you're online you're used to sudden things like popups and viruses and parents bursting in when you're Googling Lesbians Gone Wild 4 --
This guy IMs me.

He's one of those people that've migrated to the bottom of your buddy list, you know what I mean? The kind of person you may have talked to once regarding some homework assignment or other that you've never really had the balls to delete because you think having a long buddy list means you have a social life. And you don't remember why they're there. And you'd never expect someone like that to actually make contact with you again. But he did.

So he says

isllcrk88 [6:14 PM]: hey
Okay. So what have I got from him so far?

Username Seems standard enough. Bunch of random letters and two numbers: Maybe a birth year or something?
Font Default font, no webdings or any other communication problems there.
Greeting "Hey." Pretty typical. Neither suggestive nor harsh, not too formal or too friendly. Nothing to trip any alarms here. No misspellings yet, although I could be judging too soon. [More] [uncyclopedia.org]
So I click the link which goes to "Why?:Do I have a drug dealer on my buddy list?"

No, your karma's fine. Mine is now swirling down an internet black hole, as a lot of slashdot mods absolutely hate juvenile humor, while others have no humor at all, while some slashdotters hate ME. Fortunately for me most of them are trolls [uncyclopedia.org] who lost their karma long ago.

My eyeball hurts. Damn your goatse link!

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.

Re:Does it matter? (5, Interesting)

mR.bRiGhTsId3 (1196765) | more than 6 years ago | (#23012922)

I was under the impression that traffic to legitimate hosts was being lost into these black holes. Its not a dead machine, but rather bad routes being advertised for live machines. Thats general not supposed to happen, although I suppose it would be sweet if all the gunk the white holes spewed out is sucked into the black hole.

Re:Does it matter? (5, Interesting)

JustinOpinion (1246824) | more than 6 years ago | (#23012946)

I suppose it doesn't matter, but it's nice to know about it.

I've often wondered why we don't have some kind of system that when I try to go to a web-page, and it is unreachable (host down? internet down? slashdotted?), I instead am given the "last known good copy" of the site. If you combined this black-hole detector with the "automatic archives" that exist (e.g. Google's cache, or the Wayback machine), then instead of getting an error page, you could get a banner that says "host not available for reason X; here is what the site looked like on datetime Y".

Seems like this could be built into a Firefox plugin perhaps, with it automatically delivering the cached version if the host is on the black-hole list or doesn't respond after a set wait time.

(Of course, typically when I have an idea like this, I then discover that people have already implemented it. So, if anyone knows of a browser-level or system-level utility that does this, please let me know!)

arth1 (260657) | more than 6 years ago | (#23013360)

I thought a "black hole" was when the hosts were there, and you can send packets to them, but there's no packets coming back. Just like you can send mass and light into a black hole, but you won't get a reply.
In the case of Internet black holes, it's usually due to bad routing or misconfigured firewalls (which, IMNSHO, is most of them, and it will continue to be so as long as companies hire on ability to do, and not actually understanding what you do).

Re:Does it matter? (0)

Anonymous Coward | more than 6 years ago | (#23020098)

Misconfigured?? Maybe I don't want your filthy ICMP probes floating around my network. Anyways this is pointless research - I can't believe the started it and even more so can't believe they'd tell people they purpose built something to do this. A "black hole" in this sense simply means my firewall doesn't respond to your echo request. Nothing to do with bad routes or misconfigurations it's just that instead of sending you a connection denied or other fun message the firewall just discard your traffic. That saves bandwidth and cpu time, though not much of either.

- please don't forget that ICMP is a rather basic protocol and only to some very base extent a diagnostic.

Re:Does it matter? (1)

el americano (799629) | more than 6 years ago | (#23020912)

Just like you can send mass and light into a black hole, but you won't get a reply.

You can send mass and light into a planet and not get a reply. The black hole analogy is flawed, I think, especially as these routing anomalies can be temporary. And what do you call those that can be reached from some routes, but not others? Grey holes?

...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.

It might be better if they'd named these sites "boojums," because any packet that reaches one "will softly and silently vanish away and never be seen again."

4.0.0.0/9 is #1- something's wrong with that. (1, Interesting)

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... ;)

I also use 4.2.2.2 for testing customer's internet connections. With the exception of one day where something big failed on the west coast, it's always been available.

If it can't be reached, it's always the customer's computer that's screwed up(firewall, tcp stack, etc...) or they're not actually online.

Yeah, so does everybody else. Which is why, so I'm told, they occasionally change the name of the server to something like "please-do-not-steal-service.verizon.net". At least they have a sense of humour about it.

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 (0)

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?

Internet Black Hole... (3, Funny)

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.

Another kind of Internet Black Hole (0)

anwyn (266338) | more than 6 years ago | (#23017706)

There is another kind of Internet Black Hole. Imagine that you are a UFO space alien bureaucrat. You want to do routine monitoring of the Planet Earth.

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.

Idiotic Metaphor (1)

sasdrtx (914842) | more than 6 years ago | (#23031120)

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.
