They gave me F000883601 but said there's no ETA as it's still being investigated and it requires a capacity upgrade. I'm hoping maybe the 50mbit rollout will introduce some extra capacity, it seems to me that the UBR is overloaded rather than the backhaul, the extra DS2.0/a channels might help...
Anyhow at least now I don't have to worry about getting STM'd, since it doesn't actually make my connection any slower when it kicks in
