I noticed an email from their NOC last night so maybe that was due to your contact. We're investigating (and have been since this thread began).

jlivingood - This is the end of the 6th day with no improvement - is there a possible solution in the works or should I begin to move all of my websites to another server that is not affected by the comcast problem?

Thanks, Megan

FWIW, even if the problem(s) you are experiencing are a "Comcast problem" (and I have seen no compelling evidence that either your problem or the OP's problem are a "Comcast problem"), the fact that you have hijacked this thread may very well have lessened your chances of getting a resolution. It is possible that jlivingood See Profile (who started out trying to help the OP), may not have even noticed that you are not just the OP (who started out as an anonymous poster) using a different anonymous name (that does happen in these forums). Sometimes when a different anonymous user hijacks a thread, those trying to help don't always notice that there are actually two separate subthreads being discussed (and the solution to both problems may or may not be the same).

Hint: If you want help, and don't want to create confusion, start your own thread to minimize the confusion factor.

I am so sorry I have been so frustrated by the problem and was so excited to find someone else (checkerboard) who was experiencing exactly the same problem I was - I honestly wasn't wasn't trying to hijack anything - I truly thought it was the same problem and it would help. My deepest appologies to everyone for any intrusion. I have decided that my best solution will be to move my websites to a different server. Please do not stop trying to find a solution for Checkerboard because of me - he can't move the french car forum - and I am sure there are other people out there who don't know why the sites they view suddenly got slow.

Looks like it gets through Comcast fine to GLBX and then starts having problems within GLBX before it hits oneandone.net at hop 9. (204.245.39.158 is owned by GLBX.)

It may be easier to get your hosting provider to address it with their ISP as they control the routing in this situation. Comcast can only inform GLBX there is a problem, but has little control to fix it.

I am not on Comcast, I am in the US and the page loaded in less than 5 seconds. It is a rare ISP hat admits to any type of problem. They are like politicians; if their mouth moves its a lie.

iPad is not ISP dependent. My ISP installed new digital equipment and it periodically acts the same way. Let's look at your router. Which light is yellow, which is green? Are any lights blinking?

Unplug your router for 30 seconds Plug it back in and note the lights and what each is doing. On some no activity is wonderful and on others it is bad news. If it still does the same thing. Take the router off line, and check the modem. If it still slow reboot your modem. If you still can't download the page quickly......

1-) It is possible your modem, or router, or both, need to be replaced.
2-) It is possible there is a problem with the connection between your house and the first hop on Comcast.
3-) It is possible you need to move your webpage to a new host.
4-) It is also possible nothing is wrong. There could be a network issue beyond Comcast control -- and they are re-routing around it.

When it comes to electronics, nothing set in stone.

You do realize that once the packet leaves your ISP, and travels on the internet, your ISP has lost control. You do know that various nets are inter-connected (um, Inter-net) and at those connection points there are agreements for how much data can pass in each direction in exchange for money, right?

Comcast doesn't have any control (other than the peering agreement) over other people's networks on the internet. The reported speed issues here are detected by ALL comcast customers during peak times because the network between comcast and these European sites is either having a capacity issue, or the peering between it and comcast is overcapacity. It's not the CPE.

Yep... thats what I am saying... its a problem upstream of comcast. Resetting his modem isn't going to fix the problem, since I can reproduce it on my business class comcast account when he sees it.

There is nothing to apologize for; my suggestion that you need your own thread was for your benefit; it was not a rebuke.

I was just trying to explain that just because you seem to have a similar symptom to the OP does not mean that you have "exactly the same problem", and therefore, a fix for one poster's problem may not be a fix for all posters with similar symptoms.

It is just always a good idea to start your own thread when requesting help. This is especially so when you and the OP post anonymously, since it is not that unusual for anonymous posters to change their "identity" during the life of a thread, and someone trying to help may just assume that similar (but different) symptoms are being reported by the same poster.

FWIW, the reason that I keep emphasizing that you and the OP may not have the "exactly the same problem", is illustrated in the traceroute results shown below:

In the above traceroutes to the OP's problematic site, and to your problematic sites, I do not see any hops using your favorite culprit (tinet.net). I do see a common transatlantic hop using Level 3 (64.209.97.13 or 64.209.107.53 and 204.245.39.158), and all of the sites go through oneandone.net routers from my Comcast connection, but traceroutes from other locations will be different.

Hi Folks, and thanks very much for all the input... I've learned quite a few things from all of your posts! Although my original post was "anonymous," I promptly enrolled afterwards, and wanted to originally, but honestly couldn't quickly find out how to register.

This really is a dilemma for any Comcast subscriber who has trouble accessing certain European web sites. And also a catch-22 for us; unless Comcast decides to apply its know-how and leverage, we affected subscribers are but lone voices in the wilderness.

So when Imagnu entreats "J Livingood" from Comcast (as I have) to please see if it can be rectifed, I see it as both understandable and proper. Right now it's Sunday afternoon and I'd love to interact on the forum at autodejavel.fr; I have some photos from a car show to upload, but the site is again intermittently slow, up, and down.

So again, please - Comcast please fix this! Thanks again, Peter a/k/a Checkerboard

OTOH, trying to steer jlivingood See Profile toward an interface problem with tinet.net may possibly delay a resolution, since the tinet.net interface is not used by all Comcast connections to either your hosting service in Germany, or Imaginu's hosting service in the UK.

Since this thread started, I have accessed both your problematic site, and Imaginu's problematic site, and (as you have pointed out) sometimes an http connection works reasonably well, and sometimes an http session hangs busy for a very long time. But even when the http connection is hung, the traceroute transit times to both sites (from my location) are essentially unchanged.

After trying the same thing from both an AT&T and an Earthlink connection, my experience is that the extreme delays/hangs do appear to be Comcast connection specific. But with the raw transit times being unchanged during "good" and "bad" connection attempts, a resolution is probably not going to be easy or fast.

We're keeping an eye on this and doing what we can - this is largely off net and thus out of our control. But that's not unusual - so we'll keep trying and working with interconnect partners.

Thanks, "jlivingood!" The site's hung right now.

I wouldn't complain so much if it were the norm... but after 9 months of delay-free, reliable connections, I'd hate for this problem to become the "new normal..."

I've seen oneandone use TINET, GLBX and Level 3 networks in this thread from traceroute examples through different providers. The common problem areas is GLBX and it appears to be congestion/loss on GLBX overseas links. Oneandone can correct this through BGP techniques or by not using GLBX.

While NetFixer See Profile has stated "extreme delays/hangs do appear to be Comcast connection specific", this problem would be noticed on any ISP that Oneandone is reaching via GLBX.

Here is a graphic for oneandone's transit connectivity

Yes, but that doesn't seem very likely, and it could just be high latency links, since we don't know the method of connection (not satellite I hope).

The response time numbers look like what is to be expected for a trans-Atlantic connection. And I'm not certain but if they use MPLS then we are actually looking at the other end of the interface at this interconnect point.

Just to clarify, 204.245.39.158 is part of the Global Crossing (GLBX) network. Level 3 did acquire GLBX and apparently has been changing the whois IP databases; however, the router, links, etc are still part of AS3529(GLBX) and not AS3356(Level 3).

I am not sure if your problem has been included (I hope it is) but if you take a look at these two threads - it seems that one problem may have been identified and they are looking into a way to fix it - shouldn't be too long now.

I just wanted to say that the evening European slowdown problems seem to have been fixed. Thank you all very much, and thank you to Comcast for addressing this for us (especially "jlivingood")! Peter, from the Bay Area
