 xymox1Premium join:2008-05-20 Phoenix, AZ | Cox speed upgrade degraded my service So...
Some weeks ago Cox upgraded Phoenix Az to 175Mb/s D 35Mb/s up. Awesome right ?
Well it sure seemed awesome..
Some things were clearly faster... But strangely some things were not, in fact suddenly for the first time in years I was seeing odd issues, hangs and weird latency issues..
I run multiping on a seperate computer and it pings the Cox gateway once a second and records latency. Its been doing this for 5 years. I have charts for 5 YEARS at 1 ping per second showing latency and packet loss..
Up until the upgrade I could not be happier. Latency was low, jitter was low and things were awesome. But then came the upgrade.
I will let the charts speak for themselves..
This is a typical month. This is this last december. This is 24 days of charting once per second..

Here you can see where they upgraded and what has happened since. Ignore the red packet loss, just me doing stuff on the network.
Ok im sorta ok with a 15% latency increase to my gateway. What caused this is a mystery. The variation shows loading, or maybe overloading.
Whats strange about this is... Maybe Cox has added a QoS appliance and is now able to filter various types of traffic and give priorities to various things. This type of appliance introduces latencies and other issues. While I can test and download files at 175Mb/s that does not mean that FTP / HTTP get the same priority as other protocols. Gaming for example. I know people who are reporting that since the upgrade they have seen latency increase and have experenced weird issues.
Being able to FILTER content and dictate priorities of various types of traffic is a concern...
But all that would not matter to me IF IT WAS NOT EFFECTING ME. BUT IT IS...

I would like someone from Cox to explain these changes in service quality and I would like to know officially if they introduced new QoS tools into the system..
My OTHER ISSUE IS.. This chart shows latency increasing. So far we have added 3ms of latency during peak times just to my gateway during this upgrade. This appears to be increasing every day. This is significant. For gaming in FPS games this is really significant.
I cant do these charts for specific services like http or steam games or VoIP. I would like to to see if there are now priorities for certain types of services. |

 xymox1Premium join:2008-05-20 Phoenix, AZ | Also I used to get a "A" score on Ping test with 1ms of jitter. Now I can only get B and never below 3ms of jitter..
 |
|
 | i get the same b rating on the pingtest.net by default you will get a b rating if you do not run the packet loss test (assuming that your ping and jitter were low enough) |
|
 | reply to xymox1 i have also seen some latency increases while gaming and running various tests as well |

| reply to xymox1 this is on premier on a hard wired connection i remember when i ping used to be 15ms on speedtest.net

and here is my pingtest.net result

 xymox1Premium join:2008-05-20 Phoenix, AZ | With speedtest you gotta try other servers to find the best one for you. For me in phoenix the local ones are all bad. The good one is in San Diego, I2B networks..
But notice your low jitter... 1ms. When i had 65Mb/s I also had 1ms of jitter.. That has all changed..
My speeds vary from 150 to 175 depending on time of day.

 xymox1Premium join:2008-05-20 Phoenix, AZ | reply to xymox1 I really want a explanation on why my service was degraded. I wont really use the 170Mb/s but I will feel the increased latency in slower DNS lookups and the jitter will effect a number of things I use all the time.
So overall for me my service got downgraded even tho I can speedtest at 175Mb/s..
This was not what I expected. I gained speed, but lost other things. PLUS I may have had other degradations introduced that are hard to measure that are protocol and service specific. SOmething changed for people I know who game. Starting on the day of the upgrade switch they saw weird lags and increases in latency. Im told this is most obvious on FPS gaming where every packet and ms count. A slightly delayed/jittered packet is the difference in loosing the game.
There is no doubt something weird has occurred. The chart shows whatever the issue is is increasing too.
I want a explanation from Cox what has happened and what the future will bring. This change is ominous and not at all what i expected. I think Cox has introduced a filtering and QoS system and this is effecting things. |

 xymox1Premium join:2008-05-20 Phoenix, AZ | reply to xymox1 Yes I needed to enable a current Java to run pingtest correctly..
Weirdly I have now noticed that my ping test varies in Jitter.. The Jitter, Jitters.. 13ms of Jitter is terrible.. This alone might explain what gamers have been telling me. When your playing a FPS on a local server with 30ms latency, 13ms of jitter is fatal.. Mine used to be 1ms almost all the time, at times I saw 2ms.. Now its at least 3 and apperently up to 15ms of jitter to the same server.

 xymox1Premium join:2008-05-20 Phoenix, AZ | If there is a QoS policy in place, where can I read it ? |
|
 | reply to xymox1 I've noticed higher than usual jitter as well since the upgrade. I just tested and got 13ms of Jitter...it's been varying between 2 and upwards of 15 for me now, used to only be 1-3.

I know something is wrong. So far i would say my experience on Cox has been downgraded.
Maybe they are still working things out ? Maybe this will get corrected ? That would be awesome. However i dont think thats the case. I think my experence has been degraded.

 1 edit | reply to xymox1 You mentioned connection problems but showed no evidence of such. You just rant about a few ms increase in ping. oh noz!
Yet another user expecting business level service levels on a consumer internet connection.
If you want low latency, no QoS on the provider side and people to jump when you complain about 3ms, get a real connection from a business provider not a consumer offering from COX...
my connection with cox is fine.. |

15-20% increase and going up daily. Jitter up 3 TIMES and climbing..
This was a "upgrade" ?
I dont care about, and did not request, the speed increase. What i got was degraded service. Im supposed to just like that, just settle for that ? Just say its OK ?
A 50% increase in jitter and latency when playing games on a PHX based local server ? Thats OK ?
So your saying I should go spend $1500 / mo to get 100Mb/s as a buisness ? WHen I have been spending $99/mo ? just so i can get back to what i had a month ago ?
And be happy doing this ?
So your jitter is now 3 TIMES higher. Your latency drifts around all over the palce and is 15% longer. Your good with this ?
Hahaha... Your nutz..
Unless someone complains nothing will happen. |

 xymox1Premium join:2008-05-20 Phoenix, AZ | reply to xymox1 Not to mention the whole spectre of Cox introducing possible content filtering and throttling based on protocol/service.
This is BAD..
Unless there are complaints this will simply get slipped into your connection and become the new norm.
At some point maybe they will decide to block what the music/movie industry serves them a court order to block. Maybe they might decide what content you can interact with ?
Cox may have taken the first step in serious content filtering / throttling and slipped it in along with a "upgrade" in speed.
Yes i might be completely wrong. But its still interesting. Im having trouble figuring out why a switch to a wider pipe has created swings in latency and what appears as loading/overloading. One explanation is they have introduced a content filtering/throttling system. Several large ISP's have showed interest in this. |

| reply to xymox1 looking at the graphs you posted it looks like you started having issues on the 19th and it gradually got worse ,so based on that it looks as if you problem is unrelated to the speed upgrade but more that you are just having a connection issue that may require a tech visit |
|
 xymox1Premium join:2008-05-20 Phoenix, AZ | reply to xymox1 The day before my speed was 65Mb/s, the day after it was 175 and the latency issues began.. It was the day of the upgrade for my area. I will get you a higher resolution of that time frame.. |
|
 xymox1Premium join:2008-05-20 Phoenix, AZ | Starting at what appears to be almost exactly midnite of 1/31/13 or 2/1/13 the below occurred.
Times on the chart are UTC and atomic clock NTP synced
5 day width

48 hr width.. This shows some off the chart latency and a few episodes of 100% packet loss as they switched over. It also shows some low level sustained packet loss briefly..

This being exactly on 2/1/13 and my speed increase on the next day shows that something with the upgrade caused my issues..
Also, just FYI, my DPC3010 which is running on on a 6X3 channel config with current firmware shows the same tx/tx levels it did before the upgrade.
While I would LOVE for it to be a local connection issue, this seems very highly unlikely.. But sure I would be happy to have a Cox Tech check my levels and BER and look for any issues. Considering i had a perfect connection up till 2/1/13 exactly, it seems highly unlikely its just me..
I will have someone else run multiping to confirm this.. It will take a few days before i can post that as it will need to accumulate data..
I think I am also going to switch to a higher resolution ping rate to see jitter better.. Im going to set multiping to 0.3s ping interval rather then 1 s |

 1 edit | reply to xymox1 I too have started to see all sorts of weird issues. I'd like to think that it is not my equipment as I just purchased an SB6141 and an RT-N66U 3 weeks ago.
1) Some days (definitely this last weekend) there is massive packet loss in the morning. This packet loss would average about 35% loss and on every day it would auto-magically fix itself by 10:30 a.m.. This issue seems to be fairly regular and can almost be predicted.
2) Some times in the evening I will start to notice lag/latency. When I run ping tests, pinging 8.8.8.8 will fail at 100% but a ping to google.com will pass without any loss. At this same time, I can use nslookup and query 8.8.8.8 directly and receive results. This does not make sense, this should not act this way. This issue is seemingly random and I have found no commonality with it.
3) When the packet loss occurs: I run a constant ping to my router which shows 0% packet loss, I run a constant ping to my modem (192.168.100.1) which shows 0% packet loss, and I run a constant ping to the first cox device out of my modem (from tracert) and this device shows the packet loss. |
