Rubbish connection quality of VM Business line

This!

What's with the lag spikes every couple of hours, and more frequent in the evenings?

Does anyone else see this?

By docsis standards thats not that bad, are you actually noticing issues on how you use the service?

As an example when I moved from VDSL to VM, for sure the graph looked worse due to the peaks, but the actual performance was fine, full throughput e.g.

Fundamentally you'll find FTTP much more reliable that DOCSIS / "fake fibre".

Are you using the static IP service?

Oh, yes. I have 5 (it's a /29).
Same results from the router, and a Linux server on another IP.

Using the home coax cable, or an office leased line? VMB do both. The leased lines are very clean, so you can’t be on one of those.

If home coax cable are you using a Hitron modem with a GRE tunnel, there were often issues with this over the domestic planned coax cable network.

My own BQM in my .sig shows a home user DOCSIS coax cable service, very typical.

Might be a gamer, but I’d be surprised buying business to run low ping games with a set of routed IPs.

I'd be more disappointed / concerned with the low level packet loss in the evenings.

The yellow spikes are 99th percentile - only 1 in 100 packets suffers this latency, and even then only a few times a day, possibly due to your own activity (e.g. large downloads). Nothing to worry about; it's definitely not "rubbish".

The blue line is the 50th percentile latency, and that doesn't vary too much either.

However I agree that the red (packet loss) is worrying. Since TTB only measures over 100 pings it only shows 1% packet loss or greater, and that level is enough to severely affect performance, especially when downloading from places far away from the UK.

Unfortunately, this is what you get when the local cable segment is oversubscribed. It is what it is, because it depends on how the network in your area was designed and built. Some VM areas have sufficient capacity, and some are heavily oversubscribed.

Oh yeah didnt notice that, my VM didnt have packet loss.
