Latency increase for madasafish user

[#1]

Between 20CN IPSC WBC and not forgetting BT that's a lota lota of acronyms  
Anyhow since the network changes the one thing that has increased greatly for my connection is latency (ping times) so would I be right in thinking that this has something to do with the new routing compared to what went where before the WBC IPSC changeover?
Yes, I know I live a long way away from the servers

I do see step changes in the latency from time to time of a few ms. Presumably BT changing the routing. E.g. look at about 01:30 on here:

If you have seen a big jump is it because interleaving has been turned on on your line?

[#3]

Interleaving has always been "on" due to the line being 6.1 km long (according to an OR Hawk) to the 20CN exchange :), when the connection was 2Meg the ping times were in the mid twenties then upgraded to Max so ping times were around fortyeight ms now the times are around sixty ms on all the gateways I can jump onto.
I guess the main change has been going over to WBC and IPSC from the original IPStream over BT Centrals???

I saw very little change when I moved on to IPSC.

Power outage put paid to tbb BQM data collection (till I set it up again) as the IP is dynamic and not static 
Don't know what all can increase latency by that much other than changes in routing by ISP and/or BT
Didn't Entanet have some network problems a few years ago when they went either WBC or WBCM?
