Internet Partitioning - Cogent vs Level 3?
slashmicah asks: "Internet partitioning and Tier 1 ISPs are something most people don't know much about (myself included). Today, however, some Slashdot readers might have run into some issues involving these two topics. Cogent Communications and Level 3, both Tier 1 ISPs, are apparently having some 'undisclosed' disagreements, causing an Internet partition by turning-off or deactivating their peering point. Cogent Co. has released a statement explaining their side of the problem, however they have no mention of when the problem will be fixed, or when they will sort it out. This partitioning is a problem because any [single-homed] computers that are connected through Cogent Co, can not connect to [single-homed] computers connected through Level 3. Having spent all day sorting out this problem, I ask Slashdot: Isn't there a better way that the issue of peering can be handled/regulated? If not, does the future hold a scenario in which the Internet is split into several separate networks, only to be connected at the whims of large corporations?"
Reminds me on an incident that happened in Australia a couple of years back. Telstra and Optus were pretty much owned all the links outside of Australia, but Telstra lost their major one in a shipping incident. (Sharp anchors?) With nowhere for their data to go they rerouted everything through Optus to let them handle it.
Optus didn't appreciate that and promptly blocked all data between themselves and Telstra. Customers with Telstra were pretty much screwed because they couldn't contact anything and with their network going nuts even sites within Telstra sucked a lot. Still, for a couple of days there, it was two halves of an internet available in here. Was amusing to watch really.
