Just looking for anyone with actual personal experience with Cogent and their thoughts and ideas.

Thanks in advance,

Robert Marsh

Hi Robert!
From What i have heard, not a lot of people have used cogent! There have been a lot of COLO offers but I have not seen a person take one of the offers up........


Chris

I believe WildWayz on the forum uses Serverhost which has Cogent connectivity... you might want to check for a post by them.

Isn't rackshack also moving towards cogent?

I have a server located in Atlanta with Serverhost, which utilizes Cogent bandwidth. So far QWK.MON is reporting 100% uptime for the past three weeks (since the beginning). Overall I've been very happy so far, though their reliability in the long run has yet to be seen.

Yep, I do have a server with ServerHost who indeed use Cogent as a provider.
VERY fast I thought.

Doing the usual download from UUNet's FTP

My Server @ Ventures Online/Verio (Old Server)
Result: 8.13MB @ 445.08 kB/s

My Server @ ServerHost/Cogent (New Server)
Result: 8.13MB @ 2.47 MB/s

No network downtime so far that I am aware of.

All in all, I am very happy with it, so are my clients.
(and server was still accessible when LYNX died the other week)

--James

I had the local newark,NJ rep on the phone for about 20 minutes.

here are some notes:

1) any sort of service provider that is getting cogent will not pay the $ 1000 rate, they will pay the $3000 rate.

2) the $ 1000 rate is for retail companies ( non-isp web hosting ... )

3) I got to speak to 3 different parties. overall they are very happy with the service. the only thing they said bad was that the getting the fiber to their firms was slow.

just a note for all to know.

wow, can you give us the url to a file on that server?

http://www.insomnia-webhosting.com/files/uumap.tar.Z

I will leave this link here for a little while (or else all of you will suck up my poor bandwidth allowance ;))

I averaged 400k on my download from a Cable Modem to my PC..wow!

400Kbps or 400KBps? I would think the former, not the latter ... except if you have > 3Mbps cable modem? :)

cheers,
:beer:

the latter, sorry for the misrepresentation. I would love a 400k modem!

I pulled on road runner cable modem 63 kb / second ( about 2 minutes for the entire file ). which is in line with non-cache items.

by the way I did only 1 Mb to prevent wastage of your bandwidth.

eh? 400KBps > 400Kbps ....


Downloading uumap.tar.Z from insomnia-webhosting.com

From my server at VDI: 1.29MB/s
From my server at NAC: 1.35MB/s

I will create a cron job to start downloading this file every minute ... you will get a big bill this month :) j/k

cheers,

Are there any current hosts using Cogent?Like on a dedicated server or colo?

We have some servers located on cogent bw.
(854.35 KB/s) - `uumap.tar.Z' saved [8520221]

Is it just me, or do these numbers look pretty good?

When it come to results instead of rumors, Cogent look pretty good in my estimation!

Robert Marsh

I am very happy with it - not sure why people in the past have slagged it off.

One thing though, I am registered with a few website monitors and this week, all of them reported that my server was down for a few hours each day but when I check my own logs at the times it was meant to be down, it was up.

Dunno if it was an error in the US to US connectivity or what - very weird tho.

im about 100% newbie when it comes to this but, it doesn't hurt to ask opinions right?

would running a java based chatserver (a very big one) on a cogent connection be an invitation for problems? i use a couple mbs a month.

thanks

Try these files. They will route in best available path but when you download the file will route out our Cogent link:

http://216.40.243.2/onemeg
http://216.40.243.2/fourmeg
http://216.40.243.2/eightmeg

Please post results as available.

onemeg - 27sec
fourmeg - 1min 38sec
eightmeg - 2min 59sec
twentymeg - 7min 59sec

all were averaging around 40K/sec...

that's on a dual t1 at a college dorm...

onemeg - 22sec
fourmeg - 1min 41sec

average was around 40KB/sec as well, DSL line.

8mb one @ 69.82 KB/s using my Cogent server

--James

onemeg: 50 seconds.
fourmeg: 3 minutes 11 seconds.

I only got around 20 KB/sec. with my 640k DSL connection...

Downloaded fourmeg

My servers
- at VDI (Very busy, but I don't think that matters on download time): 80.25 KBps
- at NAC (very quite): 73.15 KBps

Hm ... not very impressive, especiall I can download uumap.tar.Z at 1.8MBps currently?

cheers,

I noticed lastnight that a server I was trying to tracert
in a Cogentco Noc was "down" from my ISP but when I
did a tracert from different locations around the US it
was up! Almost none of the tracerts from the east coast
would reach it but everything from the west coast did!
BTW the server is located on the west coast.

Overall I dont really think its a bad deal. Just my thoughts ;)


-- Brad

I only got around 40 KB/sec (28 low - 65 high) for all with 1.5 MB DSL connection

I am of the opinion that there is something wrong in our configuration/interface with Cogent. I've seen better numbers from other site on the Cogent network. We've opened an incident with them and we'll see how it goes.

Thanks to everyone for testing. We'll keep at it from our end.

Something has changed. You guys ought to try it again.

Wow, I just tried again, and I downloaded the onemeg.txt file in 17 seconds. I averaged about 60 KB/sec..

Can we get some more trys from various places? We're seeing posts of 150kbos to 375 kbps. Obviously, we had something configured WAY wrong.

Via RADSL through Verizon... my usual average is about 800Kb/s

So, not bad :)

(2) DS3s (Sprint & AT&T) from our network got about 640k/s while downloading:

I don't show cogent in the traceroutes to that IP though...???

Well, 400-600KB/s is definitely better than the 70KB/s I got before ... But then I will test again tommorow during peak times ...

With our BGP set up, your tracert will go the best route TO this test server. (pings same) On the way out, we have this subnet set to force the traffic out of the Cogent link.

At one time today, before we had it fixed, we were pushing over 200_ megs per second. We'll try that again tomorrow to see what happens.

So while it looks like you are going into us via TW or Verio, or Savvis or ELI, we send that traffic OUT of the Cogent link.

headsurfer,

Perhaps you should install a web traceroute program on the server so we can see what route the data is taking.

From my a box at home (AT&T Broadband cable modem in Mass):

via http (using wget):
1 meg: 171.96 KB/s
4 meg: 152.54 KB/s
8 meg: 166.46 KB/s
20 meg: 167.24 KB/s

via ftp (to the nearest 10KB/sec):
1 meg: 130 KB/sec
4 meg: 180 KB/sec
8 meg: 180 KB/sec
20 meg: 170 KB/sec

Nice speeds. About 75% of the max I've seen from here, but still well above average.

Some quick tests with the 1 and 4 meg files showed about 430 KB/sec on the server I have a shared hosting account on.

With our BGP set up, your tracert will go the best route TO this test server. (pings same) On the way out, we have this subnet set to force the traffic out of the Cogent link. I don't think so. I just checked and it's coming out Verio for me, it's not Cogent.

You deffinatly fixed something!

Your trace routes will show how you GET there not how that traffic comes back at you. We have forced that subnets traffic OUT and back to you through Cogent.

We are working to install traceroute utility on that box which will make it more clear to everyone.

HIt this link and it will give you a trace route from that server to you:

What kind of browser were you using? I had this issue with a linux browser earlier but haven't had any issues with IE. Let me know! Thanks!

I get the same thing with IE 5.5 SP2 on NT4.

-Joe

Try it again? Fixed a couple glitches, it turned out that if it wasnt getting through after a certain hop it would start erroring out like for instance the machine I was trying it to had a firewall so the packet wasn't making it through and the time out wasnt working properly.

I'm on a different computer (IE 5.5 on Win2000), but it looks fine now.

-Joe

edit: It also works on the machine I was using yesterday afternoon (IE 5.5 SP2, NT4).

I get about 170KB/s average on the 20 meg file.. Not bad..

-BW

Your trace routes will show how you GET there not how that traffic comes back at you. We have forced that subnets traffic OUT and back to you through Cogent. Well, how about putting up a file on a server that also traces on a Cogent Line? We show it coming out Verio, not Cogent.

rackmy.com,

what's wrong with the tracroute showing the route taken from that server to our IP? I don't understand this, but how in the world would we be able to do traceroute (hence, sending packet originating from us) to a server to know which route a data packet from that server will reach us from?

chees,
:beer:

A trace from my machine to the server goes via TWtelcom... but, from the server it goes via Cogent.

With BGP, we have little control over what path the traffic comes to us over as we now have 5 possible paths into our network.

However, by controlling the default gate on out routers, we can force the traffic out of the desired path.
