Packet loss - area 15

Hello,

For the past week and a half or so, I've been experiencing intermittent lag spikes when gaming. I found out it was due to packet loss, and have replicated the issue on multiple devices on my home network, both wired and wireless, pinging to a range of servers. See the below:

I contacted Virgin's customer service team, who despite my protestations said a) packet loss cannot be controlled by an ISP, and b) that I might need to contact their Gadget Rescue team to resolve the issue (at a cost).

I've since seen here that there seems to be multiple people impacted by packet loss in area 15, but I wanted to know if there is anything in my router logs which would point towards an issue on my end before I (try) to take this further:

Re: Packet loss - area 15

You are not alone... I first had this problem on December 23rd.

Another user thinks it should be fixed tomorrow:

Re: Packet loss - area 15

This is definitely Virgin's fault, as the packet loss happens between 2 hops on their internal network. Your router is fine and there's nothing you can do.

I'm also on area 15 and this has been happening for around 2 weeks.

For an hour or so today, I was getting 80.0.0.53 (hari-core...virginmedia.net) ) as the first hop to google.com and no packet loss to it, but a lot of packet loss (verified by a simple ping -t on windows or ping -n on Mac) to the second hop (something-else...virginmedia.net).  Currently I'm getting packet loss to the first hop as well, but the packet loss is so bad, even tracert can complete succesfully.

Re: Packet loss - area 15

There is no way whatsoever that you can tell of pack loss on a ping. Some routers on a ping do not accept Ping (ICMP) packets and you eventually timeout and go to the next router. This is NOT packet loss.
