120M Peak time latency increase (PL6 - Plymouth)…

kev445 · 12-02-2014, 09:53

We’ve recently been upgraded to the 120Mb service, slightly prior to this we were upgraded from 6 to 8 downstream and from 1 to 2 upstream channels. Immediately after the upgrade in channels, we saw our peak time latency steady out.

Since then we’ve had the odd evening where latency has increased by a small margin, other nights it doesn’t increase at all.

All of a sudden within the last week, I’ve noticed our peak time latency on our TBB graph has increased considerably… It isn’t like peak time latency we’ve experienced during previous episodes of congestion, take a look:

Speeds during this time are odd, some sites we only get 1-2Mb and others it’s the usual 120Mb (using speedtest.net and the TBB speed test)!

I live in Plymouth in the PL6 area code… Our train line has been washed away recently, one theory is that some of Virgin Media’s fibre has been washed away, reducing the available capacity???

it is possible that some of VMs infrastructure has been damaged meaning that there are now more of you in your area using less capacity. Why don't you post a message on the VM forum and ask them what is going because I doubt the ming mongs in India will have a clue. "bad weather? what are you talking about, it is nice and hot over here"

That graph shows typical core network saturation. It is possible they're having to re-route via backup links that have reduced capacity as you say.

For the last 10 days, i've had packet loss on the upsteam around 20:30-21:00 every day, it lasts about 10-15mins then just goes away and the line is perfect again. On the weekend it happens approx an hour earlier but lasts about 30mins more, during this time i can watch youtube/streams fine, but playing games, using voice communications is useless.

I'm not sure it's just the Plymouth area.

Same here in Southampton, fine off peak 2000ms pings peak time, india denying it says nothing wrong

I told him of people complaining of same thing on there community forum but he didnt seem to care.

they sending engineer tuesday who because he'll come off peak will probably find nothing wrong!

So frustrating, glad im out of contract, BT Infinity looking very tempting right now.

Almost a week later, it is still happening… I haven’t reported it as a fault, as I can’t be doing with the hassle of trying to communicate with them.

I must admit, that if it wasn’t for the occasional speed test (only some speed test sites are affected) and TBB graphs, I wouldn’t have actually picked up on the issue.

Graph for the last 24 hours:

I think that iam getting a similar issue in Torquay iam having awful issues watching video from various sources sadly I have had to resort to using a vpn get watch anything,iam also having speed issues on various speed test servers this happens between 6-11 pm every day.According to Virgin Media there is no issue i guess i must be imagining it ive included my latest thinkbroadband graph below the packet loss between 12-2 was a failed software update

That looks like exactly the same issue I am experiencing.

If I have some time this evening, I might investigate further and submit my findings to their forums.

The reaction you received from Virgin Media is the kind of the response I assumed would happen. If it isn’t a utilisation issue, they don’t seem to know how to diagnose the issue further.

Thank you to everyone else who has responded to my post, it’s much appreciated.

Iam glad its not just me if you get a second can you do a speed here its based in Amsterdam in peak time im currently getting 80-100 meg but come 8pm it will be down to 3 meg. thanks

I think the issue maybe fixed to a certain degree will keep on testing over the next few days

As the issue is with the core and/or routing, then it will only affect certain sites/servers/routes, and doesn't have anything to do with your own connection.

Hence, CS will likely not see a problem if they check your line since the problem has nothing to do with your line. First-line support probably wouldn't understand core network problems anyway even if they could actually access the required interfaces to diagnose them.

That sounds like a very good diagnosis of the issue no wonder i felt like i was hitting my head against a brick wall with the fault
