Fusion/Flexlink Voice Issues
We are currently experiencing issues with in and outbound calling through our voice platform. Our engineers are working on identifying and resolving the problem ASAP.
– Noc
Update: All call issues should be resolved as of around 1:50PM. We are presently working on a root cause analysis and will provide more information as it becomes available.
Mail Cluster Degraded Performance
At approximated 17:15 this evening, one of the 4 clustered enterprise class filers that handles email storage started to show unexplained high CPU utilization leading to slow I/O performance. Â This may have resulted in slow interactive performance or even some timed-out connections for POP3 or IMAP for approximately 25% of our users. 15 minutes later we issued a partner takeover, and a few minutes after that, a partner giveback to affect as clean a reboot of the affected system. Â At this time things seem to be behaving normally but we are keeping a close eye on these systems.
-Kelsey and Nathan
Update: This issue is ongoing and we are working to resolve. We have no ETR at this time. -Kelsey
Update: We believe we have identified the source of the problem and resolved it for the time being. It looks like the root cause may actually be a software defect of sorts in the IMAP server and not the filer. -Kelsey
Major Core Power Work
Update (3:00AM): Â This work has been successfully completed.
Tomorrow night, Tuesday October 15th, beginning at 11:00 PM, we will be performing major power work within a core datacenter in Northern California. While we expect no customer impact during this procedure, due to the length and nature of this operation we are starting earlier than normal but plan on taking on the potentially intrusive work after  midnight.

Emergency Equipment Maintenance
We will be performing emergency maintenance shortly on equipment serving Legacy DSL customers in the Los Angeles area. Affected customers may see up to 10 minutes of downtime while the work is performed.
-Tim
Update: Maintenance work has been completed and all affected customers should be back online. We apologize for the downtime.
Updates to Our Recursive DNS Servers
On the morning of  Tuesday the 22nd, we will block access to our recursive DNS servers from off of our network.  This will help reduce the use of our DNS servers as part of the ongoing DNS Amplification Attacks as well as protect their quality of service for all of our customers.  This will, however, cause issues for any roaming device that has our DNS servers hard coded.  These devices should be configured to use server assigned DNS settings instead.  For more information please see our forums.
