Fourmilab: Running on new leased line
The switch-over to the new leased line mentioned in yesterday's posting is now complete and Fourmilab's Internet connectivity is restored. The technician arrived a little early, so the switch was done about 15 minutes before the scheduled start of the window at 13:00 UTC. The entire service outage was only about five minutes, as opposed to the estimated fifteen—there were a few brief subsequent interruptions of a few seconds each as we moved cables to their permanent locations. The new line is the same speed as the old: 2 Mbit/sec symmetrical, but there will be a minor performance increase since the new router runs its Ethernet port in full-duplex mode, while the one it replaced ran in half-duplex mode, resulting in collisions and the need to re-transmit packets.Posted at
