Governments are mostly administrative. Running your own servers is 'real work' which mostly gets contracted out. Used to be necessary to have your own servers because that's where the software your administrative people used ran. The government could build it's own power plants, and hire the employees to run them. Probably cheaper/easier to contract that out (eg, buy power from power company).
