AS174 predates PSI; it was NYSERNet's AS.

The hows and whys of PSI retaining it when they were no longer under
exclusive contract to run NYSERNet (starting in 1992) probably boiled

detailed commentary to people who were actually on the inside at the
time, if any of them still read nanog.  Cole?  Mitch?  :)
