[Outages-discussion] Internet Outage Hits Time Warner Customers in southern California - now up

[Frank Bulk]

Which is why I make a backup copy our leases file every hour.  I've had to
rebuild my leases file once from the ARP/host tables of our BRAS and CMTS
and the next 48 hours weren't pretty at the helpdesk.

Unless you're actively dividing up the scopes across various DHCP 
servers, generally you're relying on a centralized DB to store the 
bindings so that all the DHCP servers can source IPs from a common 
pool.  All the clustering in the world doesn't help you if the DB itself 
gets corrupted.

Not saying that's what happened here, but it's a scenario I've run into 
in the past.
