[edit] Need for cleanup
The article reads like a corporate ad. Needs cleanup more encyclopedic tone. —ERcheck @ 02:48, 20 February 2006 (UTC)
[edit] Defacing!
ogent keeps defacing this article and inserting false statements about themselves.--Tomthebomb193 13:58, 21 April 2006 (UTC)
[edit] about time you got some up to date imformation on here
Cogent should have sued for the trash that had been posted on here about them. Ever hear of slander? No frills teir two provider, my ass. —70.187.244.217 01:09, 26 April 2006 (UTC)
- Hello... "no frills tier two provider" is exactly what Cogent is. —198.252.182.170 20:10, 3 May 2006 (UTC)
[edit] Potential Section on Tier 1 Status
There seems to be a bit of controversy over whether Cogent is a Tier 1 network. Therefore, before adding this section, and removing "Tier 1" from the description of Cogent, I am posting my proposed changes to be discussed:
While Cogent Communications is one of the largest providers of connectivity, it technically is not a Tier 1 provider. To be a Tier 1 network, every network it connects to must be either a customer's network, or a settlement-free peer's network. Cogent Communications does not pass this test, because it pays for transit from Verio in order to connect to some Tier 1 providers. However, it does not neatly fit into the category of a Tier 2 provider, because unlike a traditional Tier 2 provider, it has settlement-free peering with at least some Tier 1 providers. The Level 3 is definitely a peer, and Verio is most likely another peer.
It should be noted that while a Tier 1 provider is usually associated with being able to provide a higher quality Internet connection than non-Tier 1 providers, this is not necessarily true. A provider that paid to peer with every Tier 1 network would have access to the Internet at roughly the same level as a Tier 1 provider, but by paying would be disqualified from Tier 1 status.
Any comments? Techieman 07:06, 29 April 2006 (UTC)
- I noticed that much of the description of Cogent as a tier 1 provider and other details in the article are simply a verbatim copy from Cogent's about page. I don't think this text, straight from Cogent's PR, should appear in the Wikipdedia article. Jnk 19:43, 3 May 2006 (UTC)

- Also, unless someone can verify that Cogent is no longer paying for transit, then regardless of what they claim on their website they are not a Tier 1 carrier by the commonly accepted definition. I believe they are still paying Verio for transit [1] [2]. Jnk 03:56, 4 May 2006 (UTC)
[edit] My viewpoint
Well, we can't say they're Tier One, because they pay for transit in a few cases. I would think that being Tier One and Tier Two would be absolute things - if you pay for any transit, you're Tier Two. If you don't pay for any transit, you're Tier One. But really, I think there would have to be a "Tier 1.5" designation of sorts, because Cogent does do a lot of free peering. --Tomthebomb193 03:00, 3 May 2006 (UTC)
To verify that they purchase verio transit simply use their lookinglass on their website at www.cogentco.com and do a traceroute to either www.aol.com or www.sprint.com. Neither buy bandwith from verio but yet both are reached from cogent via verio. —Jwvo 19:07, 4 May 2006 (UTC)

- It's being routed through Verio/NTT America's network (hop 6). If they had peering with Sprint-Nextel it wouldn't have gone through Verio. —Jnk 23:31, 4 May 2006 (UTC)
That trace route also is consistant with the AS-path visiable to customers of Cogent (I was a BGP speaking cogent customer until about a month ago). —jwvo 13:55, 15 May 2006 (PST)
[edit] Change re: Ethernet vs Internet
Note to changer, fine by me, but that change was made by the Cogent people I.e. they claim they are an ethernet provider. :-) —65.96.165.213 22:02, 3 May 2006 (UTC)
[edit] definately NOT a tier1
they buy transit (from anyone). they are not a tier1.
[edit] "No-frills"
According to this [4] (dated, according to their site, 29 April 2005) Gartner have stated that Cogent has [a] "no-frills approach" [that] "has its risks." -- Karada 22:14, 3 May 2006 (UTC)
Here are some facts about Cogent:
- 1. Cogent purchased many of Verios assets, including most of their T-1 customers, plus some of their Data Centers. Cogent no longer buys transit from Verio- this information is OUT OF DATE.
- 2. Cogent is currently ranked as the 5th most peered backbone, as defined by the number of unique A/S numbers with which they peer- currently around 1475 peers. This ranks them behind only the "Big Three" telco's and Level3.
- 3. Cogents Backbone is an Ethernet backbone, they sell Fast Ethernet and Gigabit Ethernet services, thus they are indeed the largest ETHERNET backbone in the USA as measured by the number of ethernet ports. Yes they are also an Internet Service Provider, and offer Type II services, such as DS-1, DS-3 and OCx services in addition to their Ethernet services.
- 4. Cogent has bought up the assets of 13 defunct ISPs, including PSINet. They are now traded on the NASDAQ under the symbol CCOI.
- 5. Cogent may be "no-frills" but when you can buy a 100Mbps Internet connection for $1,000 a month, who needs frills? Especially when the bandwidth you're buying is guaranteed!
I hope this information helps clear up some of the misconceptions about this company.
Cheers! —149.127.109.2 18:54, 4 May 2006 (UTC)
- I see you are connecting from PSINet, are you a Cogent employee? From all I can tell Cogent did not buy Verio's backbone, but only bought 2400 of Verio's T1 Customers. "Cogent will acquire the majority of Verio’s T-1 Internet access customers and associated equipment. The transaction includes more than 2,400 business customers." [5] Can you provide us with an external link verifying that Cogent now has a settlement-free peering agreement with Verio - or that Cogent bought Verio's backbone? —Jnk 19:37, 4 May 2006 (UTC)
[edit] Should be locked and/or have an accuracy dispute disclaimer
In light of the persistent vandalism (some of it traceable to Cogent, and I don't use the term vandalism lightly), shouldn't this article be appropriately marked with a disclaimer that its accuracy is in dispute and locked so that non-registered users can't edit? Same comment will be made in talk for Tier 1 carrier —Ke4djt @ 04 May 2006 (UTC)
[edit] Primary Customers
Can anyone provide some documentation to back this up before adding it back?
- ", including the Adult Industry, and the Unsolicited Commercial E-mail industry, otherwise known as spammers."

Spamhaus lists four of their IPs on the SBL http://www.spamhaus.org/sbl/listings.lasso?isp=cogentco.com, mci.com is currently the top spammer ISP with 214 addresses on the SBL. Cogentco does host Michael Lindsay http://www.spamhaus.org/sbl/sbl.lasso?query=SBL36056 who has been kicked off of at least 3 other ISPs for spamming. So they don't seem to mind hosting spammers, I don't know if it is accurate to say that most of their customers are spammers though. This evidence says nothing about the adult content hosting, but there are sites such as http://www.gofuckyourself.com where someone could research this.
