Weird BQM Artefact

Hi All,

Looking at my BQM last night there was a period of packet-loss followed by a period on increased latency (from 0200-0300)

What is odd is that Roger_Gooner on here despite being at the opposite end (ish) of the country - has exactly the same thing at exactly the same time!

Does anyone know what would cause this?

Cheers

Re: Weird BQM Artefact

I noticed that on my own BQM, and a couple of other live BQMs in the forum, although they weren't all showing EXACTLY the same start time.  It would seem likely from the implied phased impact and small hours timing that it was a planned traffic routing change whilst some piece of internet equipment was changed.  You can see it isn't altering the peaks which are mostly the last mile DOCSIS connection, but it is increasing the minimum latency by a regular 5ms.  That change might be on VM's network, it could be internet traffic routing to the TBB servers, or even maintenance on the servers themselves involving load shifting to an alternative DC say 40-50 miles further off.

Re: Weird BQM Artefact

My BQM looks exactly the same even though we are on hub sites well over 100 miles apart. I suspect that this is more about TBB servers rather than something happening in VM's core network.

Re: Weird BQM Artefact

There's been a few of us at different parts of the country that suffered 4 distinct drops between 0300 and 0600 hrs on the 15th Sept

Re: Weird BQM Artefact

Yep me too.  Resegmentation perhaps?

Re: Weird BQM Artefact

It won't be a resegmentation as this involves splitting a node to drive fibre deeper into the network served from the hub site, whereas what we are seeing goes across multiple hub sites.
