1st gen Cavium TunderX to retire
It's an old chip and I am not surprised that it is being retired. Perhaps they waited for a worthy successor - there are few on the horizon as of now, but it will be little longer before the new hardware can be installed in the datacentres. They also won't be cheap, which makes them hard sell for bare-metal. In the meantime, the old bare-metal instances are turning out to be pain for the users and maintenance staff which is not surprising.
