56kbps Data to most places; these were interstate tail circuits. There
were a LOT of them (staffing issues drove this; unless you TRUST the
engineering staff at a remote office, you either get a telco to build the
router backbone -- in which case you have to trust THEM -- or you home-run
the lines back to your location, aggregate them into T1s (or, if you have
enough, one or more T3s) and then do the channel bank or frame-relay
last-hop connection to your data center.
This was not a typical Internet-provider type of thing. We had financial
real-time transaction processing going on -- with direct interaction with
the public. If things aren't working in <that> environment you are REALLY
in trouble, and VERY fast.
With that situation "it'll be up in 15 minutes" isn't good enough. You
want and need 24x7 availability with no ifs, ands or buts, and you do all
reasonable things to get it.
