Intermittent DHCP Issue

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.

Fresno ATM Backhaul Issue

At 1:08 AM today, our ATM backhaul circuit to the Fresno area went down unexpectedly. We immediately began diagnosing and troubleshooting the circuit with AT&T, but before we could isolate the problem, the circuit came back up, approximately 10 minutes later.

We are currently monitoring the circuit with AT&T, and apologize for any inconvenience this brief outage caused.

Los Angeles ATM Maintenance

This Thursday, March 26 at 12:01 AM, we will be inserting a new card into our core ATM switch in Los Angeles. This switch handles all DSL, Business-T and FRATM connections in the Los Angeles area. No impact is expected, though the hardware insertion may require a reboot of the chassis. If this is necessary, all DSL, Business-T, and FRATM customers in the Los Angeles area will suffer 5-10 minutes of downtime.

-Jared

Update: The card insertion has been completed without incident. There was no impact to any customers.

PHP url_include removal

Monday March 30th we will be disabling the url_include ability in our default PHP setup in order to improve the security of our web cluster. This ‘feature ‘ of PHP is frequently misused by web developers and is the by far the most common vector used by hackers to gain access to exploit customer websites. Web hosting customers that require this functionality have several options to either work around or re-enable it presented in further detail in a FAQ at http://www.sonic.net/support/faq/advanced/url_include.shtml

If you think you may be using this feature we urge you to review your php code before March 30th and make any necessary changes to ensure that you will not be affected.

Update: We have completed the changes to php on our web cluster. Please note that at this time these changes only affect customers using the default php configuration.
