Unbearable Ping Spikes

[paulmaggiemcd]

I've had this problem for ages now and had multiple attempts at fixing it, however they never worked. I decided to just leave it for a while, as I've seen that to be a suggestion, and see if the problem fixes itself. I assumed the issue wouldn't still be present and I feel like I'm wasting my time.

I've seen multiple people with the same problem and have heard Virgin's service is over subscribed, but hoped that was resolved.

Your problem is Docsis and no good QoS for the upstream as you have many people in the area upload and the delay for you to send a packet buffers with everyone or maybe some people have their PC's infected doing DoS.

The problem got me thinking of another problem if no DoS was happening and that is VM could QoS after Docsis as a whole and that they try to limit and QoS upstream that matches four lots of 64 qam but if one person on them four channels has a 16 qam then VM would need to QoS as if everyone was on four 16 qam...

BQM looks like a typical over-utilisation fault.  The outlook is not good.

Hi Paulmaggiemcd,

Thanks for your post, I am sorry you're having this issue with your broadband services recently. 
I have had a look at your services on my side and can see there is an area outage, which is regarding an over utilisation issue like @Andrew-G mentioned.
This is due to be fixed  - 30 SEP 2021 13:00 - but please be aware this is just an estimate, it could change depending on what the engineers find. However, I am sure they will be working incredibly hard to get this fixed as soon as possible for you.
Thanks, 
Megan_L

Just curious if there is any reason as to why my internet seems to be better over the weekend compared to in the week? I would have thought it would be the other way around.

School summer holidays have started.  And with so much working from home, that's created new patterns of demand, and particular pressure on upstream which is more evident during the week.
