August 2, 1972 VM/370 was announced. I was in Mrs. Isaac's class at Salford Hills Elementary, so I wasn't there, but it changed my life. Happy Birthday #zVM

Hello friends, we opened a new #zVM red alert today for a problem when you apply the PTF for 4TB. There is no functional problem with the new code, just an unexpected challenge applying it to the system.

This post presents an estimate of how much the āminimumā MTU costs on the Internet, and itās scary.
The 1500 byte MTU is the scourge of data centre networking as well... how inefficiently is your network operating if youāre not using jumbo frames?

"Why is the MTU of Ethernet 1500 bytes?"
A question I asked myself a few nights back and could not find a quick response to. So after many days in a rabbit hole I present:
