Has anyone else seen 5 hourly packet loss?

[prs1000]

This one is a little odd. I have been on FTTP for a little under 3 months. Ignoring the fact that I am waiting to get on my local BNG, my connection has been pretty good. I get the full download and upload speeds most of the time. I get zero packet loss according to the broadband quality monitor.

3 or 4 days ago that changed. I started getting the occasional red spike on the BQM showing 60% packet loss. From the 12th December it got more regular. Actually it got VERY regular, which is what I find curious.

From 7am on the 12th, I got the 60% packet loss spike and then another spike every 5 hours up until the most recent which was at 9am today. It isn't roughly every 5 hours. it is EXACTLY every 5 hours. On the hour.

Clearly something somewhere is scheduled to happen every 5 hours. I thought maybe it was my Asus router so I changed over to a TP-Link router. No difference. 

Obviously I am going to call Vodafone about it but I don't have a spare couple of hours until later today. Has anyone else seen this? I don't have any devices that schedule something for every 5 hours so I am assuming it is happening at Vodafone's end.

.@prs1000 For the moment, would you do a trace route to a well know destination outside of Vodafone's domain  (e.g. bbc.co.uk) please? With the identification of where the network thinks the best route is may help relate your problem to others that have been noted recently.

Yes it appears anyone running bqm is reporting the same, but the connection appears fine so could actually be thinkbroadband. If you go to the gigafast 900/900 latency thread already mentioned it there and a suggested alternative checker which does seem to back this theory up

Ah, thanks for the info. That has saved me wasting an hour or 2 talking to Vodafone 😉

I wouldn't waste time going through the useless checks they will ask you to do from their scripts. If they wont escalate your problem, then I would suggest raising a complaint. Complaints Code of Practice | Vodafone UK

It's unlikely to achieve anything, but it might get the management to realise how bad things are.

Edit: I replied before I had read the possibility it may be ThinkBroadband at fault.

Yes that wasn't a call I was looking forward to.

Will need to monitor it some more but it looks like it is vodafone as my two graphs show the same packetloss at 14:00 so in that theory next due at 19:00

The 6am one on the thinkbroadband was me resetting everything wondering if it was my kit

[ZinGeRs]

Packet loss again showing on the graphs bang on 19:00 so next one will be at 00:00 very bizarre. As I was game playing during this time and my son was twitch streaming and daughter on Netflix nobody seemed to notice a thing

Same here. Spike at 7. No obvious effect
