We've had two incidents of one of our L2TP LNSs locking up over the weekend and causing disruption to some L2TP connected customers. Therefore will be swapping over the hardware in the morning of Tuesday 8th August at around 6AM. At this time L2TP sessions will be dropped and then re-establish shortly after on the new hardware.
Cancelled! Following discussions with FireBrick developers we've decided not to swap the hardware in this case. The fault is likely to be software related and instead we've changed the LNSs configuration slightly and are working on adding extra debugging in to the software which will be loaded once that coding work has been completed, which should be in a couple of days time.
