@Chris, I hope you don't mind me butting in here, but you might want to liaise with Bob Pullen on this issue. He and I have had a number of PMs in the last week or so, and he has been dealing with my fault - 130769591.
At present both the 209.x.x.x and 51.x.x.x subnets seem to be experiencing problems. I switched to an 80.x.x.x subnet thanks to a static IP at the weekend, and have had no further packet loss since. While there isn't a correlation between the 209 and 51 subnets in terms of the IPs (Bob tells me one is ARIN, the other RIPE), there is a correlation in that they're both on the new network.
This isn't a local issue - I've had an engineer visit to my home yesterday, who confirmed no issues between myself and the exchange, and no issues with the connection itself. Bob has also let me know there is a line card due for replacement on Thursday that could be having an impact for these issues, and he would let me know the outcome.
Basically, the problem is on your end, not ours. I understand you needing to follow the script and make sure that everyone's on the same page, but there are a number of people in this forum reporting exactly the same issue, and where they've posted traffic graphs, they look exactly like mine did a week ago, and still did before I swapped to static.
Please, please, for the sake of good customer service, accept the fault is somewhere on Plusnet's end, and get it resolved. I don't mean to have a go, but until I swapped across to static IP I'd had almost 3 weeks of the same issue, going through the same story without Plusnet accepting that maybe, just maybe, it wasn't on my end.
