Tier One ISPs Dying 394

xbmodder writes "Two tier one ISPs are down today. At about 23:30PST both Verio and Level 3 starting having problems with routes. According to Level 3 this is a software upgrade gone awry. Is this the end for Level 3?" Many, many reports about this are coming in, and if you're wondering why the stories were rather sparse overnight, it's because it's difficult to post them without internet access. Hope everyone else is back online too.

      Way back in the day when I was a Network Controller at BBN Planet, if we began to have cascading routing outages we'd call it "Flapping"... Visualize a wounded bird squirming around on the ground flapping...

        I'm sure you know this, but for the rest: "flapping" is the common term for when a router's routing tables rapidly cycle between two invalid states [cisco.com]. The dead bird analogy is pretty descriptive, but the term "flapping" has technical and not allegorical origins.

        That's not accurate. Lots of tier 2 and lower providers own their infrastructure. The important qualification of being a tier 1 ISP is that they don't pay anyone else to exchange traffic with them. The tier 1 guys are all predicated on the idea that they are huge enough that none of the others of them can afford to not have good and direct peering with them. Level3 can't afford to not be peered with MCI, and MCI can't afford to not be peered with AT&T, etc. So they all peer for free with each other. The

      Tier 1 are the huge ISPs, which peer with eachother (and don't pay eachother transit fees) and sell transit services to smaller ISPs (which do pay fees to send traffic through the Tier 1 ISPs). So yeah, bandwidth wholesalers is pretty accurate. See this wikipedia article [wikipedia.org].

      In 1994, The National Science Foundation (NSF) awarded contracts to replace the National Science Foundation Net (NSFNet) Internet backbone. These contracts were for backbone transport, routing arbiter and traffic exchange points (NAPs).
                These contracts were awarded for the original 15 NSF sponsored NAPs, and to become a Tier 1 ISP, you had to have atleast DS3 connectivty to all 15 NAPs.
                It's a very old and crappy definition, and I wish people would stop using it, because it is very easy to meet now adays, and most of those original NAPs are now insignificant, compared to the power of the force.

        My understanding is that a Tier 1 ISP is now defined as one that has established free peering points with all other Tier 1 ISPs.

        Considering that free peering is likely only established between 2 networks that have close to a 1:1 bit exchange, this is a very high bar to meet.

      This is not _just_ their server being down, this is the entire network of two tier 1 carriers [wikipedia.org].

      The (basic) implications of this is that a good chunk of the internet as a whole is inaccessible to the rest of the internet.

      We're not talking about just a server. We're talking about the entire ISP's networking capability. Tier 1 ISPs own huge swaths of networks-- literally miles and miles of cable, and sometimes radio and other links. They route the traffic across these lines.

      When a Tier 1 provider goes down, their customers go down too. That picture on the Boing Boing page shows a list of the Tier 1 providers. Every ISP that is NOT a Tier 1, gets their access from a Tier 1.

      People speculate that Level 3 is dying because they've been making some really bad decisions lately, resulting in a lot of outages. A couple of weeks ago, they actively filtered out traffic from their competetor, Cogent, over a dispute from how much to charge at the point their networks exchanged traffic (called a 'peering point'). Now this. The rumor is that the company is in financial trouble.

        It's not a rumour that Level 3 is in financial trouble - it's clear for all to see. They have crushing debt repayments right now.

        The Cogent spat isn't over yet either - Level 3 are going to de-peer Cogent again on November 9th. They are trying to force Cogent to pay for transit, but right now it looks like Cogent holds the strongest hand and Level 3 will be once again forced to back down.

          The reason that Level 3 isn't happy with the peering arrangement currently is that it's not even remotely even. Level 3 sends almost nothing over Cogent's network and Cogent sends over a vast majority of their traffic through Level 3. A peering agreement is based on the premise that the companies will be sending almost equal amounts of traffic through each network. Level 3 has been analyzing that for a time now but the last straw was when Cogent had a sales blitz targeting Level 3 customers saying that they would dramatically drop their prices to almost nothing to get them to switch away from Level 3. They are now also using the downtime that was experienced due to the peering problem in their advantage even though Cogent is in the wrong. Cogent knew about the depeering and did nothing to resolve it.

            Oh yes, I'm aware of all of that - but (generally speaking) Cogent has the content, and Level 3 has the users. Guess who catches the most heat from the de-peering from its customers - Level 3 - as their customers will tend to see the problem first.

            I predict that Cogent will do the same again as well - not lift a finger to fix the problem when they are de-peered on November 9th, and Level 3 will probably end up being forced to re-peer as customers whine that they are not getting the whole Internet and threaten to take up Cogent's free 1 year offer.

    Noticed this this morning when a customer called upset about his hosting services being unreachable. A quick traceroute showed one of level3's ip to be down. A few minutes later more customers had problems with different routers from level3. As soon as I saw level3 I knew enough, shrugged it off and told the customer that it was routing problem we couldn't fix but those responsible were most likely already trying to fix it.

    It seems fixed now though, so no, this isn't the death of the Internet just yet.

    While this only lasted a few hours, it still caused a mess across the North American Internet during those hours. The point is a small amount of big networks are responsible for over 90% of the traffic on the Internet. If alter.net went down it would be total chaos. If just one of the major peering points went down, sure the traffic would be rerouted, but overloading the other points at such high latency that it would be almost unusuable.

    Is this even an issue? I mean, this was probably scheduled maitenance that went a little longer than expected. I have been through this before. It just sounds like Level 3 dropped some core routers for a few minutes to do a code upgrade - it didn't work so hot, so they were down for a few more mintes, OSPF/BGP decided to tell all the clients that they have no routes, Level 3 gets the routers back up, OSPF/BGP tells everyone that their fine again. Was this like 6 hours, or 45 min?

      It was maybe 2 hours or so before new routing tables started spreading to bypass Level3's and Verio's networks, and afterwards it started stabilizing again, then it seems Level3 has since then woke up again. The XO network also had routing troubles from this btw, maybe more too. Sites and services such as AOL, SpeakEasy (when asked, they were stumped and could only say it affected all their customers, hehe), Google, and Wikipedia had access problems depending on where you lived during this timeframe.
