The Suddenlink transit looks okay. Latency issues, maybe, in Internap Network Services Corporation (PNAP) transit.

Explain what problem you're experiencing? Are you saying the latency is high? 55ms isn't bad by any means. If that is the problem, what is it usually?

Wow, I'm in Central Texas and get 51ms to that IP. 55ms from within California seems a tad excessive, but I suppose that a congested link somewhere in the path could slow things down.

Considering for the past 8 or so months that i have had service (that worked)- my ping to this server (a game server i run) is usually 15 or so , 55 is really high, - then when you take into consideration i am being routed through GERMANY?!?! at 89.149.184.149 and 77.67.79.58 i would say my routing is a problem - thank you for any help!

Where is your game server located?

I am in Arcata Ca. and the server is based out of Los Angeles Ca. When i first had suddenlink installed i was having these routing issues - i would be sent through Kansas and the east coast then back to LA - I was on the phone for a few months and had numerous people out to my home until i found this forum and SDL L3Tech was able to help me. Heres to hoping it can be fixed again. thank you.

* Norman - your ping would be alot better to that ip if you were not routed through Kansas either.

Those are Tiscali-owned IP addresses; but the nationality of the owner does not indicate the actual location of the router. 'xe-3-3-0.lax20.ip4.tinet.net [89.149.184.149]' looks like it is in Los Angeles, California; and, in any case, latency to Europe from the U.S. West Coast would be closer to 200 ms than the 26 ms to 77 ms of your trace.

There is no law requiring that European-owned companies can't run routers in the U.S., or that they must not use RIPE IP addresses on their hardware.

If I were routed through Kansas my "ping" would be closer to 60 ms. By examination, my 1st through 6th hops are in the south S. F. Bay Area (San Jose/Palo Alto). The latency on the 7th through 12th hops is about right for a direct run to the Los Angeles region. If I had Fastpath DSL, my latency would be about 15 ms lower throughout the trace.

Just so i am clear - when i looked up th ip address under an ip locator -

6 25 ms 24 ms 24 ms sonicnet-customer.xo.com [216.156.84.101]

That ip is not located in Kansas?

That is a Sonic.net customer facing XO Communications IP address. XO Communications may be in Kansas, but Sonic.net, LLC is a relatively small (about 50,000 subs) Internet and telephone (POTS) provider serving California customers in the AT&T service areas of California within the state. It is a CLEC.

That IP address would be assigned to XO hardware in San Jose, California.

Do not trust Internet IP geo-locators. When I was an AT&T customer, such services put me in various locations from across town (the Monterey Highway address was about halfway between my actual residence and Morgan Hill, California) to across the Bay (variously, Pleasanton, San Ramon, and Novato). None were within ten miles of my actual residence, and one was close to 75 miles away!

If it's supposed to be under -20ms then i'm betting that the return path is coming back in somewhere other than California. On your game server that you run, run a trace-route back to your public IP and post it here (you can omit the last hop to keep your IP confidential). That should tell us where it comes back in at.

I am currently seeing 20ms from the CMTS to that destination. Is this problem occurring intermittently or just during peak-time?

Please download and install Pingplotter pro (free trial), run it for the next 24 hours, then attach the sample set to this thread.

I have noticed it a non peak times, but not as much, but at peak times it is constant. I have just downloaded the program and will post the results tomorrow - thank you very much for your time!

Perfect. Thank you!

First of all, the packet-loss (shown in red) is patterned which indicates some form of ICMP rate limiting, likely on your router. From the CMTS (hop 2) to the private IP of the cable modem and it shows 0 packet-loss a s seen below:

CMTK01#ping {removed} repeat 5000

Type escape sequence to abort.
Sending 1000000, 100-byte ICMP Echos to {removed}, timeout is 2 seconds:
Success rate is 100 percent (5000/5000), round-trip min/avg/max = 4/8/10 ms

Second, according to the PingPlotter graph, the latency is occurring between hop 2 and 3 and only occurs between 6pm and 11pm. Let me dig deeper into that and figure out what's going on with that. I'll PM you on here when I find out.

thank you for your help, is there anything i can do to help the packet loss? or no? - thanks again!

Since it's just rate-limiting ICMP, then it's really just cosmetic and should not affect any real traffic.

Edit: You can either figure out where the setting on your router is to disable the rate-limiting or you can temporarily bypass your router and run pingplotter while directly connecting your computer to your cable modem. This should remove the rate limiting from the PP trace.

There could be some real packet-loss in there but since the rate limiting is already causing so much packet-loss, it may be hiding it.

Change PP to use different protocol? Noticed the setting early, never tried it to see what happens, lol

My guess, is the fact in his name, its level 3, when you call the call center, thats like level 0 to 1, and they send stuff to level 2 if you are lucky, and then the level2s end up sending stuff to level 3 again, if you get lucky.

This is my total guess. I also don't think there is a level 4

Actually, the L3 stands for "layer 3" which is the network layer of the OSI model (»en.wikipedia.org/wiki/OSI_model).

I do not work for a call center. I am a routing engineer.
