I'm with you, imagnu. Something has radically changed for the worse just 5 days ago, and like you, I wrote to tinet.net. However, all they said to me was that they didn't finad any issues with their network (see below) and sent me their tracert routing:
"After further investigation I do not find any issues on our network that would cause the packet loss that you have reported. The following is a copy of our trace route monitor to 85.165.110.194.

| Yep - I agree John- it works for a bit and then stalls out. I am on it now, and it was normal, but now it's back into its crawl-speed. It only partially loads the section called "le Citrojournal," stalls, and then 30 seconds after, it fully loads. |

| Read in depth the sites JohnInSJ  has posted. The problem is the site design where it needs constant refreshes of many elements and right now some of them are failing to promptly update (could be the server or user demand)
As you note it changes at different times of day, but during the worse monments by the time the slow element is served the other elements need updating and the process starts again.
Lock your css, limit the refreshes, limit or cache the graphics and it runs pretty well for a site 8K miles away as the crow flies |

I also noticed with this tracert oneandone is also a shared route - maybe that is causing some of the hangup. |

If you look closely at their tracert - they did the test at 6:59 am - and as you and I have been saying all along is that everything works fine from 3am - noon or 1pm - it is in the afternoon and evening that the real slowdown occurs. Oh well I can only hope it will get fixed soon. |

I am currently designing a sample website for one of my clients - I haven't even optimised it yet as it is only a sample of a possible design and it got an 83 out of 100 on the google speed test
»developers.google.com/speed/page···le=false
and this evening it won't load at all or sometimes only loads the words - it is not a complete website but the front page slide show should still work - it is so intermittent.

| I have noticed that some of these speed tests wait until the entire page has pre-loaded through the last slide in the slide show - but the page appears loaded much earlier than that.
As I mentioned before - this site is under construction and not optimised yet - not worried about the speed - only the fact that nobody who uses comcast can view it or many of my websites during the afternoon or evening hours - while all of the rest of the world without comcast can see it no matter how long it loads.
And for the past 14 years I have not had any problems and suddenly for the past 6 days my sites don't load for people using comcast between the hours noon(ish) to midnight(ish) est |

Sure, but I was noting how this showed even off comcast, latency to the US was very high, and much worse in CA. So whatever trickle of bandwidth is supposed to get allocated to comcast is likely fully consumed.

All I am saying is why has this only started 6 days ago and been fine for 14 years - yes I am sure all sites can be improved - but that does not answer my question about why now, and why only comcast - when my sites can be viewed anywhere else in the world on any other isp - and have worked great on comcast up until 6 days ago - nothing has changed with my sites - but suddenly they do not work in comcast. |

You're missing my point. The peering agreement comcast has with tinet.net, or congestion on tinet.net itself is the issue. Either there is something that changed in the peering agreement, tinet.net is having issues, or there is something flooding that link (specifically across comcast and tinet.net) at night that didn't used to be there before.
I am not saying it has anything to do with your web design. Note how the latency from Ireland is 4 seconds (not going across the altantic via tinet.net) vs 2-3x slower for all US sites?

Sorry - I am not trying to be argumentative - I am just frustrated. I do appreciate all advice and coments - I understand some of my sites can be improved in their speed - but that still does not answer the question why the same one worked fine last week and is not working this week.
Something is different and it is not my websites. Once the thing that is different can be identified then maybe it can be fixed. I am just trying to find out what it is. Thanks again for everybody's coments and assistance. Megan |

Yes - I agree - maybe something like that - maybe something new using up most of the bandwidth - but how do we fix it?? Thanks |

You're correct, I exit Comcast to the OP's site in San Jose/Great Oaks just as you do, but.......... I jump on Global Crossing to OneonOne Net/kundenserver.de. No problems the several times I've looked at it.
Going to imagnu's site, even Tinet is not bad until it gets to Amsterdam.........
Interesting that a French car site is hosted on German servers though........

Yes - I agree - maybe something like that - maybe something new using up most of the bandwidth - but how do we fix it?? Thanks We don't - that's up to comcast and tnet.net. All you can do is host your sites someplace with better peering agreements. Which I understand isn't an option for you. Comcast is aware of the issue said by jlivingood: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).
so hopefully some monitoring will turn up a problem/solution.
