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.

Your image hasn't been moderated yet but I posted about something that seems very similar. Unfortunately I managed to post it in the Landline section 😉 

My issue also started on the 14th and happened every day except one since then.

@prs1000 "My issue also started on the 14th and happened every day except one since then. "

Interesting.  Do you notice any effects on your quality of service?    Do you also get the apparent packet loss indicated on the graph?  The image is showing now, I think. 

[prs1000]

No, I haven't noticed any impact on the service. I took some speed tests around 9pm last night and the speed tests were normal, including the ping reported by the speed test. 

Your image still doesn't show for me

Moderation of images is a real nuisance at times, especially given that  my link was refused on grounds of faulty HTML!!

The top of the graph shows a continuous red, zigzag line. I'm not sure what that indicates.

[prs1000]

They were just moderated. They look exactly the same as mine apart from the zig zag line

I'm sure we won't be the only ones, but unless folk monitor their BB Quality they may not notice anything.  

Folk can set up a quality monitor here.  Think Broadband Quality Monitor

As of this evening - no change.  The 'blip' is still there, with the solid zigzag red line. 

Over the last few days I have done speed tests at different times of day.  The only effect upon speed performance seems to be during the speed test. If I test during the evening blip the test runs very erratically with the speed oscillating wildly. Other times of day the test runs smoothly. Jitter levels are around 7ms. Normally jitter is 1 ms at most. 

The next step is to figure out if activities such as gaming and streaming are affected. I shall monitor that over the next few days, but this evening one of my son's is experiencing lag on Call of Duty - Modern Warfare. He has never experienced lag since we switched to VF FTTP. 

[prs1000]

No change here either. Have had no packet loss though. Just the congestion type pattern. My gaming days are well behind me. Nothing has been impacted. I did give a live streamed training session a few days ago and didn't notice any issues. No subscribers reported buffering or any other problem.

I just now tried to contact VF by phone, whilst the problem was apparent, but no one was taking calls, I next tried the BOT who put me in a queue of 9  to talk with a techie. After 90 minutes I got to position 3 , when a message came up saying 'we are no longer here'! 

VF are a disgrace!!
