Client just updated their FIOS to 300/300. Out of the ONT their feed goes into a Cisco SG250-08 (as the phone system needs to be pre-firewall, yeah I don't get it either but the Toshiba installer did it this way.)
Once the FIOS speed increased, the traffic to the servers dropped from 150/150 to 13/88. Did the usual checks, rebooted the usual stuff (ONT, Watchguard.) Nothing made the speed increase.
On a lark, we rebooted the switch and bam(!), 300/300 server side.
Why would the switch, working at 150/150 for a year, slow down the traffic to 13mbps incoming when the outside edge speed increased and what happened internally during a reboot that suddenly allowed it to flow at 300?
