Yes and no. If your DB is an internal app for a company where the users
are in the same building as the servers, doesn't matter really I guess.
Meteor hitting the building would kill the users in addition to the
server so nobody will be calling you to complain about system downtime.

If your app is used by external customers who are all across the
country, they want to continue to still use your software even though
you and data center #1 are 6 feet under due to an 8.0 earthquake. They
want auto-failover to data center #2 which is in close proximity to CIA
headquarters and other juicy terrorist targets.
