I've noticed for months that most of the time latency to the AMS servers is problematic.  This example is representative of several route tests that I did today.  Something's wrong as the latency difference between hop 12 and the endpoint should be negligible.  I hope @Staffcan look into it.  🙏

Hello!

We do not see any problem, as you can infer from https://airvpn.org/servers/Piautos/ and https://airvpn.org/servers/Alrai/ (also consider that we have excellent round trip time, like 25 ms, and no issues with mtr even from residential ISPs in Italy, go figure...).

Check the tables "latency" (it's round trip time really) to and from locations and you will see that they are normal all over the world. Does anybody else experience this problem? Please feel free to report here, on this thread.

Kind regards

I cannot build lft since the website redirects to HTTPS without port 443 being open on the webserver, but with TCP traceroute:

# traceroute -T alrai.airservers.org

I don't even get to be routed through Cogent. I suspect it's a routing thing with your ISP.

Well, that's what I intended to do was point fingers at Cogent or GlobalLayer.  The trace clearly shows the problem is with them and not even my ISP as the latency to Paris and Amsterdam (hops 11 and 12) is normal.

But just for more information for Staff, here is the info from the routes checker for all the Air servers back to me :)  You'll see that all the AMS servers have abnormally high (about twice as high) latency compared to other European locations.

Does anybody else experience this problem? Please feel free to report here, on this thread.


No problems for me from the Netherlands, residential landline. Today I am in Belgium, different mobile ISP, no probs. No problems from my VPS in Ireland (AWS).

Check this table for each NL server (in the screenshot: Piautos) to verify that the problem is on your ISP side only.

As I said, the problem is obviously with Cogent.  Are they my ISP or yours?  And if the problem were on my end why would only the AMS servers be abnormally latent for me as seen above?

Note how both go through 130.117.50.206 and 204.68.252.53 as they make their way to the endpoint.  Now, for me, 52ms to Paris and 60ms to AMS is normal - the abnormal latency starts after.  But for the ping from globalping there's no big jump in latency between 130.117.50.206 and 204.68.252.53 like there is for me. 

Remember, the routes test of all the servers showed abnormal latency to my ISP only for AMS servers.  So, there seems to be some relegation by Cogent to and from my ISP or my region, etc.

Please feel free to contact your ISP for the alleged issue with Cogent.

If you need more info, this is our provider with AS49453, see also https://www.peeringdb.com/net/5372 for the public peering exchange points and interconnection facilities. Also Cogent does not serve IP transit to our Alblasserdam servers or AMS-IX directly or the other exchange points we rely on, so it's a serious misfortune that you need Cogent to reach the servers.

We can't help you directly, we're sorry, but we can help you indirectly by showing that the problem is not on our side of the infrastructure and by providing you with the relevant data to have your ISP investigate. It must also be said that Cogent has a sky high amount of peering disputes and malfunctions, please check https://en.wikipedia.org/wiki/Cogent_Communications. It may be relevant in some cases (check NTT for example).

Kind regards
