| High latency between 8-11 est?? anyone else? This has been happening for a little longer than a week now and it is driving me crazy. I am a gamer so latency is something I am always tracking and something that is important to me. Recently I have noticed in prime time ours servers that I normally have a consistent latency of 30-35 ms shoots up to minimum 90's even as high as 160's. That server is a chicago data center. Normally I connect to a LA data center which use to average 80-90 that is now in the 250's - 300s and completely useless to me.
I have upgraded to boost bought a brand new router (linksys e4200) connect wired tried bypassing router all together nothing works. DL speed is also very inconsistent. I can see anywhere between 50-60 mbps during day but prime time its as low as 7-11 mbps. All ive gotten after several calls is your signal is good. A technician is finally coming today but my fear is since this is happening at specific times there is nothing that will be done to fix it. I live in North NJ, anyone else experiencing this? |

I had the exact same problem. Unfortunately a tech visit is most likely not going to solve it. It is probably node saturation. What you need to do is collect some documentation. Take a look at the link below, setup some smokepings and document your latency over a week. If it peaks during prime time hours you have a saturation issue. The only way I was able to get it resolved was to connect Wilt via email over at cablevision. E-mail him screenshots of the smokeping pages, HFC mac address of your modem and just a general description of the problem. He can escalate to the proper people within cablevision.

| Have a technician come out during the evening hours, and ask for a supervisor visit as well. |

I have the same problem you described. During peak hours my ping increases from about 15 to 70-80 or even 90-100 on weekends. I too have a brand new Cisco E4200 router. I have also bypassed the router, and the issue still occurs. My signal levels have been solid and I've had 40+ days of uptime. My bandwidth isn't really affected during peak hours, only my latency.
I've performed a trace route,and the jump in latency always occurs 3 hops out from my router. Can you post a trace route taken while this is occurring? |

Yep. This has been happening to me starting right after Christmas. I have extensive data supporting the evidence of the problem due to a server running Smokeping at my house. The latency increase isn't at the cable layer of the network. It's in the backbone. The first couple of hops have low latency, then the latency jumps quite a bit inside CV's network. I explained this to them multiple times in the direct forum, but they just tell me to contact support and have a tech come out in the evening to check it. They don't seem to understand they need to check their backbone link utilization in their network leading up to my node. That's where the problem is for me. It's quite apparent. I'm too busy and not home enough during sane hours to get a tech out here when I can be here to check it. |

Hackettstown, NJ | This is a much older sample of data, but this is what I was seeing:
1. router.abellohome.net 0.0% 7 0.3 0.4 0.3 0.5 0.1
2. ???
3. dstswr1-vlan2.rh.rndhnj.cv.net 0.0% 7 10.4 9.9 8.7 11.6 1.1
4. ???
5. 64.15.6.118 0.0% 7 32.1 37.6 32.1 47.2 4.8
6. 18267805.cst.lightpath.net 0.0% 7 33.3 37.5 33.3 42.2 2.9
7. adfb66fe.cst.lightpath.net 0.0% 7 39.4 37.9 34.6 43.7 2.9
Hop 4 doesn't respond with TTL expired so I don't know what the latency is between 3 and 4, but going to hop 5 it jumped over 20ms. This was toward the end of the problem one night. I've seen it jump as high as 90ms higher than the 3rd hop. The 3rd hop latency is always low for me when this problem happens. Everything after it is high and it always happens typically between 8PM and 10PM or so... I'm in the Allamuchy, NJ area. |

1 edit | Ironically I've been complaining to Cablevision about the same exact thing...right after Christmas with the latency. I've contacted Wilt twice...had OSP clean up noise and problematic equipment on the poles but yet no change. Nice to see exactly where this is happening and will forward your info to the 2 supervisors along with Wilt and see what happens. I'm in the Morris County system. |
