I remember using ICMP data to bypass my high school's firewall. TCP and UDP were very locked down, but they allowed pings. It was slow though - I think I managed to get a few KB per sec. Maybe there's faster/fancier firewall bypass methods these days. This was back in the 2000s when an entire school would have a single OC-1 fiber connection.
155mbps Telco trunk line for a school? Nicer school than I went to.
Around 50Mbps: https://en.wikipedia.org/wiki/Optical_Carrier_transmission_rates#OC-1
I only had dialup at the time, and the fastest home broadband available was 1.5Mbps ADSL, so it was pretty fancy!
