[Speed] My French Car Forum is Being Throttled - But Why?I joined a forum six months ago, based in France, for lovers of old Citroen cars. Two days ago, the site has slowed to a crawl. Here it is: » autodejavel.fr I have tried the site from two ethernet-connected PCs on my home network, (Comcast cable Hi Speed) as well as via wifi - same problem - very slow download (like 60 seconds or longer). ALL other sites- even other French news sites like lemonde.fr, work at blazing speed. But not autodejavel.fr ! The website's admin guys are not experiencing any delays or lagging in France. Really Important: on my iPad 3 with ATT LTE, the site works lightning-fast, no problem whatsoever. The website autodejavel.fr is never a busy site- maybe 20 active posters online - and has always been instantly responsive. Can anyone please try the site and let me know? Thanks, Peter I use IE 9 and Speedtest.net shows about 24Mb download speeds. Thanks very much! |

I'm on Comcast as well (have the performance w/powerboost package). I usually get 24 MB down and 4 MB up on speedtests. I clicked on your link almost 10 minutes ago, and the page still has yet to load for me. It has not timed out yet, just still trying to load. I wonder if its a routing issue? I know ping tests don't say much, but look at the time it takes. Seems high to me. Here's a ping to the site. Note that it does reply, but has a high time (avg 144 ms). ping autodejavel.fr

Comcast doesn't throttle. The problem is probably due to the unique French engineering, similar to that which went into their fine automobiles such as Simca, Alpine, Peugot, Renault, and Citroen. Considering, you're lucky you can get to the site at all. |

I am on a Comcast 12/2 connection. I clicked on your link and the site loaded in about 4 seconds. Certainly not the fastest loading homepage I have seen, but considering that it is probably a low budget site and had to travel across the Atlantic to Middle Tennessee, I would not consider it to be "throttled". Try going to some of the Taiwan computer parts sites if you want to really see slow load times.
If you are still having problems, then the problem is probably in the routing between you and the site. Try doing some traceroutes to see what the differences are between your connection and mine. Here is a traceroute from my location:

Hi Brian- and thanks for trying the site. Comcast is definitely doing something here.
Again, the site loads super-fast on my iPad 3 with ATT LTE cellular connection... but is almost dead with Comcast. I wasted 40 minutes talking to four Comcast "support" people, three of whom tried to sell me the Signature Plan for 79.95 and $20. per month. I refused, and they could not offer anyone to help me out for "free." I'm at my wit's end! |

Acchhh.. I've been frequenting the site autodejavel.fr for six months and never, ever had this problem. And the locals in France tell me the site's as fast as ever. And yes, the Citroen DS is temperamental, but exquisitely comfortable and a real work of art!
And by the way... Newtown, PA? Meet you at the corner of State Street and Washington! Kidding... moved to San Fran in '94, but grew up in Bucks County, Council Rock HS '75...
Now please tell me if I'm wrong here -why would my ATT iPad3 work as usual, but Comcast "throttle back" or otherwise slow down the site?? Thanks! |

It could be due more to routing from the various networks. My first recommendation is to register as a user here so I and others can PM you. The second is to post a traceroute from the ATT network and then immediately (same time of day) post a traceroute from the Comcast network. I'd hold the French car thing against you except that the DS is pretty neat and I'm wrenching on an old British car tonight with friends, so I really shouldn't cast aspersions on other cars since the Brits haven't historically been known for their reliability. |

So, the site may have lots of crap on it (which isn't loaded on a mobile browser like your iPad3) which slows it to a crawl. On comcast, my linux box, firefox with noscript blocking all the crap, page loads in about 1.5 seconds. Even allowing scripts it seems to load in under 2 seconds. |

For what its worth, I did try the page this morning, and now it loads in under 5 seconds. Did not actually time it, but it is way faster then it was last night. When I posted my reply at 21:04:43, I waited at least 15 minutes for the page to load before I gave up.
So, something was going on last night in regards to the path the bits were taking to get from me on Comcast's network to them.
It appears that whatever was "broke" is now fixed (as far as the actual load time of the page). I did not try to "download" anything from the actual page (like a file posted in a thread) so I cannot say if that is working any faster then it was before. If the OP has a link to such a file download, post it and lets test that out as well.

said by Checkerboard21:The site, by the way, is acting up again, after running at full speed since the morning! Sounds like evening congestion. How is your speed on domestic sites? Comcast jumps through lots of hoops to reach internationally hosted sites so congestion along the route is a problem. It's acting slow for me right now so that is what i suspect. |

I would have to agree here. Site is slow loading for me as well (not like it was this morning). It would have to be evening congestion on our end I'm thinking, as it is what....2 or 3 AM in France (if that is where the site is hosted). Things should be really quite over there at this hour.

I have been experiencing the same problems viewing sites in the UK for the past 3 days now - it is really bad in the afternoon and evening but ok after 3am until about 12 noon. When I did a tracert the only common route was the tint.net and that was where the slowdown showed up on mine as well. When I connect through my phone at&t as a hotspot the speed is fine - just when I am on comcast and only for 3 days now. But just wanted to mention it isn't just a car site in france. |

tinet.net is Inteliquent, a long haul transit network. Comcast swaps data packets with them to extend their coverage with other ISPs. It's a mutual benefit called peering. Apparently Inteliquent may be the slow down as Level 3, used by at&t, isn't affected by slowdown. It's fast on Comcast's backbone until it hits Inteliquent. |

Wow- thatnks for getting to the heart of the problem. The site is once again fast this morning.
Any idea how to get Comcast's attention in order to address this? As I mentioned earlier, all they'll offer is to sell me a Signature Service subscription. |

Damn, this is frustrating. Any idea as to whom I should contact to get it addressed? It constitutes (for me) a radical reduction in service quality.... |
