At 11 AM today we proactively failed out of service a DHCP server that serves DHCP to some DSL customers in the Bay Area and Sacramento area due to a RAID disk failure. The DHCP traffic fell back to our backup DHCP server. Unbeknownst to us, the backup DHCP server had a hardware issue that was causing it to respond to DHCP lease requests slowly, thus causing intermittent DHCP service to the affected customers. We have restored the primary DHCP server while we diagnose and repair the backup server. We apologize for any interruption of service that this DHCP issue caused.
