Zarjaz, I was told that the "lift and shine" just moved my connection to another port on the same rack and that was carried out on the 7th October at 3.30pm. I'm being told that the TPM moves my connection to a different rack entirely
That is correct, but highly unusual for this just to be done off the bat, usually the result of a visiting SFI engineer (you know the type

) requesting it and carrying it out as part of the visit. Are you able to confirm that you lost sync around 3:30 on the 7th ? A proper TPM will give you a fair length of no service.
