I pressume you mean that after reconnecting to the master socket that this made your latency worse... NOT your line stats?
Each time you connect to Virgin, there is a strong chance you will connect via a different Central Pipe (what Virgin call a BAM and the only ISP that calls them BAMs). As mentioned in one of my earlier posts reconnecting can sometimes mean that you will get on a better Central.. but on this instance you may have connected to one that was even busier than the previous one.... which would fully account for the increase in latency times.
You can check which of their BAMs you connect to from the 2nd hop of your tracerts.
>> I did try the f8lure ping tests
f8lure normally requires a static IP.. however if you sign up with somewhere like
dyndns, then you should be able to use that to set up a test.
Ive just been able to set up a new f8lure test for a dyndns name... simply type in your dyndns address rather than your IP. eg
username.chosen_dyndnsname.com.
It took about 5-10 mins for f8lure to update to the new account name but its now showing as live and graphing ok.
Dont forget because youre on a dynamic IP youll also need an update client running on your PC such as
one of these. Must admit I havent tried that particular one as Im on a static IP
