Sort of related to the thread, been having issues with rises in the average latency at peak times and even during the daytime sometimes. Had a thread running on the VM forum about it.

Apparently it's down to an increase in upstream traffic but not enough to break the threshold for escalation.
Anything latency sensitive is not great when these rises occur (gaming etc.) Seeing as they don't want to do anything about it, I'm having a FTTC connection installed. It'll be slower on the download side but hopefully more consistent latency wise.
