Re: What do you make of these ping and traceroute figures?


[re: meditator] [link to this post]
 
IMPORTANT

The effect of Windows 10 on the networks varied, hence why the four BQM I posted were not identical. Of course it may be that there was an additive issue, i.e. not just one thing affecting their network but lots of others.

As things stand now with the handful of Vispa BQM have running everyone say a 30 minute window of packet loss around 6:30am GMT and variable latency between 30 ms and 140ms plus looks common during the evening, plus some packet loss.

Cause unknown, but an ISP will know where traffic is going from and to, even if it cannot tell exactly what it is, e.g. is this youtube streams, or Akamai cached content or torrent traffic or BBC iPlayer etc

Accepting fully that response times (latency) can vary depending on exactly where you're sited in relation to the host, this doesn't appear to be anything to do with congestion per se, as pings to the BBC website conducted by one or two other people at various locations around the UK have returned figures of around 17 - 20 msecs, with hardly any variation in the figure over a 24-hr period. As I reported earlier in this posting, I ran some pings and traceroutes at around 6am in the morning, the results of which demonstrated that this problem was not down to normal variation in latency over a 24-hr period.

BTW, when I first reported the problem some two weeks ago, VS told me in an e-mail later in the day that "their supplier had identified a fault and was in the process of fixing it". VS posted the same piece of news on their HelpDesk, on their website. At that time there were others contacting VS reporting the same thing as me.

Are those pings taking exactly the same trace route?

An ISP will peer out over several links and it is feasible that one may be bad and one may be good. Don't see enough Vispa users to know what their normal routes are to different places off the top of my head.

In reply to a post by MrSaffron:
The BT Wholesale stuff will NOT run at all if you are not on their network so yes you are BT Wholesale based
Uh uh Andrew.

That was the change when they introduced the new Results page and put the graphics and IP Profile boxes into the new "Further diagnostics".

The initial test runs on any Openreach line. All the Further Diagnostics button does is pick up the sync and IP Profile from the BTW databases just as before to give us the original results page.

The error message the poster described is what is given, as the phone number isn't recognised.

This is why I asked the OP to run both stages. I think he is on LLU.

The indispensable man or woman passes from the scene, and what happens next is more or less the same thing as was happening before.

Here's a traceroute I performed last night.

7.50 pm, Wednesday.

Traceroute has started…

traceroute: Warning: www.bbc.co.uk has multiple addresses; using 212.58.246.55

11 bbc-vip046.cwwtf.bbc.co.uk (212.58.246.55) 31.195 ms 31.083 ms 30.817 ms

Notice that the large latencies we saw some days ago within the Vispa network have - at least for the moment - disappeared, and that it's actually as we go more into London that the latencies now pick up. I strongly suspect that, as a result of me complaining to Vispa so much the other day, someone - either at Vispa or BT themselves - has juggled the routing.

BT are out of the equation before hop 2 (hop 1 is your router)

Yup, I realised that.

I think from hereon for a while it'll be a matter of me monitoring the latencies day to day, and seeing whether the long ones return again.

Fri 21st, 10.14am.

Here's a traceroute I've just done. Things have certainly improved since the beginning of the week, and right now the latencies are very reasonable (especially so, considering that this is a busy time of day). At present, the greatest delays seem to be nowhere at all in the Manchester area but instead are in the London zone. Looks like BT have done some more hands-on management and have significantly improved the situation.

Traceroute has started…

There are no delays in the London area in that traceroute, it's totally normal. One hop didn't respond to ICMP but there's nothing particularly unusual about that.
