I got this e-mail from Rotman’s IT Help Desk:
Please be advised that some European websites are unreachable from the UofT network due to a dispute between internet providers Cogent and TeliaSonera.
Cogent is the internet provider for the University and one of the largest in North America. TeliaSonera is a major provider in Nordic and Baltic countries. Until this dispute is resolved the following geo-locations may not be accessible from either network. Traffic that has originated on either of these networks has been blocked regardless of other network paths (3rd parties) that may be available to each company. We will keep you up to-date as we receive new information.
For anyone who want’s more information (like me) you can check out this blog. Excerpt:
In the past, when Cogent got into a peering fight, it fought with other tier 1 providers who felt that Cogent shouldn’t belong to the exclusive club. Tier 1 providers have “settlement-free” peering between each other, meaning nobody pays anyone else for network access.
As you can imagine, this can save a lot of money.
Cogent is the company that other Tier 1 providers love to hate because it has the lowest prices, 100 Mbps for $1,000 per month (yes, that’s $10 per Mbps).
Now, GigaOM is reporting that Cogent is no longer linking with Swedish backbone provider Telia because Cogent wants payment from Telia for peering.
It seems important that these guys figure out some sort of agreement. This type of silly fighting just gives customers a reason to go pay a slightly higher price for their internet access. Eh UofT? *wink* *wink*
