Regular evening blip.

[Anonymous]

Has anyone else noticed this odd blip in their TBB quality monitor?  It occurs around 8.pm daily, but with no obvious effect on speed or latency, given that this is a peak time?  I would note that during the test the speed is more erratic than usual, fluctuating wildly up and down, but settling at just over 900Mb by the end of the test. The first occurrence was 14th March. Here's this evenings snapshot also showing the blip of the previous day. 

The continuous packet loss at the top of the graph started yesterday at 1.00 am. A ping to BBC.co.uk shows no packet loss.

Here's my ping and tracert to the BBC.

@prs1000 OK, they will monitor the line today. He says he has made some alterations that may resolve the issue. We'll see.

As a matter of interest, what region or city are you in? I'm in Coventry. BNG = Birmingham.

@Jayach   If, as you say, this is due to evening stress on the network, then the network isn't fit for purpose, only 18 months after it was installed in our area! You would have thought CityFibre would have planned and hoped for a large take up. Also, why did this begin only on 14th. Match and has happened everyday of the week since then? What's changed? I'm guessing it is more than just evening stress.

I was suggesting the stress is on the Vodafone network, not CityFibre's. I'm on FTTC (so Openreach) and see the same "blip".

I see.  That would make sense.

Either way,  I have engineers  here now. (1.30 pm) They have picked up "light levels" higher than they should be on the property end of the fibre cable running from the pole - a reading of 33dBm.  At the pole,  the reading is 13dBm, so they are replacing my cable and also the external wall box because that was "too small for the job" of housing the spare cable.  The property end light levels in the house are now an ideal 15dBm.  (Should that be dBm or dB?)  Speed is fine,  and latency 5ms. 

If  I still have problems from 8.00 this evening then your explanation sounds even more likely.

That's a fast response from CityFibre.

Yes, amazingly quick.  4hrs from the end of the call to VF.

I seem to be having a similar 'blip' on openreach. Just stopped the traces from my router to see if the BQM will pick it up. I'll report back later. 

[prs1000]

Tonight’s “blip” started 2 hours sooner than normal.  Everyone else see the same thing?

[Anonymous]

Yep. Despite work by CityFibre earlier today, the blip is back. As reported it has come earlier this evening.  Game play laggy for the boys. 

The big red line on my graph indicates downtime whilst CF engineers were here. At times when the blip is not evident, the work they did shaved my average latency down to 5ms.  

I will get onto VF first thing tomorrow, report the lack of progress and the fact that multiple reports of the blip are coming in from different parts of the country and from different local networks such as Openreach.

I hadn't realised that the BQM I posted earlier is actually "live" (didn't know you could do that) but it shows it is just starting for me.
