Tonight, at midnight, we will reboot one of our DHCP servers that handles legacy DSL customers terminated in San Francisco onto a new kernel.  The server should be down for only a few minutes and little to no interruption of services should occur for the 2,700 affected customers.  This update will resolve a problem with an Ethernet transceiver lockup affecting one of the servers redundant uplinks.
