A retired IT Eng & Ex GE/Honeywell South East Asia Network Manager. My engineering implimentation established the 1st commercial online time sharing service from Australia to GE's super centres (IBM & GE mainframes) in the US, way back in 1970.
The international link via satellite ran at the blinding speed of 2400bps & was a shared link for all the Australian customers of this service. It was updated to multiple 9600bps links via both satellite & under sea cable. A vast improvement compared to the first commercial link.
I also operated & ran my own network design, implementation and support company for 15 years, supporting large commercial Australian networks.
I still fix PC's in my spare time for family, friends & others.
