Note: these are the primary systems that carry the load for our service. We have several other servers that are used in development or for archiving of data.
Internet Backbone Connection
Our services are hosted at a "Colocation" facility at One Wilshire Blvd. in Los Angeles, and service is provided directly on the backbone of the Internet via fiber cable. No intervening telephone company (e.g., Verizon, Sprint, or AT&T) is involved.
Availability of servers, power, and Internet access is monitored by software on these (and other) local servers, which automatically send alarms via text message in the event of a failure. An additional Internet connection is provided by Comcast Cable to provide a path to the alert system (and access to the facility) in the event of an AT&T failure.
Our "up-time" is monitored and scored on a quarterly basis, evaluating the availability over the past 12, 24, and 36 months.
A current PDF of the last report can be viewed Server Availability and Reliability (SAR) report (uptime).
