Ive had my monitor up n down for almost 2 years, ive never seen such neat lag spikes, they look like someone is downloading/uploading at the connection speed limit for a very short burst (like speed tests) the parts between the spikes look level, run some TRACERT's with command prompt to bbc.co.uk see if there are any spikes in ping along the route. as its a UK based host it should be pretty consistent low pings across all the jumps.
Here is my QM
And a friend on 100Mbits on a different exchange.
As you can see by these not brilliant at all.
This is my copy paste TRACERT.

As you can see, some of the jumps time out some of the jumps have massive difference in each successive ping reading. This explains my lag in BF3 and other data intensive FPS games, and other data intensive MMOs such as EVE online. it may seem pretty stable, and only every now and then that it happens, but this is what causes the massive spikes. Jitter is the killer for VM connections.
When i was on Landline ADSL2+ i never had a jitter over ZERO, even when i was having internet problems. my average jitter at LOW USAGE TIMES like 4.30am is about 5ms jitter to 30ms ping to UK based tests, at peak times 2pm to 10pm 50-100ms ping and 10-30ms jitter.
Over saturated network running on 7-10 year old technology = all round terrible service.
Note that both you and my friend have the EXACT SAME double red line packet loss, at the EXACT same time, are you in Birmingham? i have a similar spike, that isnt exactly the same, but is at the correct time. This is TYPICAL of VM issues showing on one connection tend to show on MANY connections.
