The thing is, this old flaky line is ok for a day or two, then will have a brainstorm. Once things were looking good yesterday, Adam at Pulse8 put me on fastpath and as you saw, all looked good with the expected lower latency. It stayed good yesterday with all hell breaking loose once again today. CS responded very quickly to my mail this afternoon and switched interleaving back hoping it would put things back to where they were yesterday, but not so. The only answer at the moment is a switch to fibre bringing my copper down to 300m. A job to justify when at other location a lot of the time, but it's unusable at times as it is and P8 have no contract tie-in for fibre, so will suck it and see next time here giving them some lead time. Still engineer install with them also.
