All critical path equipment and servers have power backup.
Every site actually runs on two servers.
However, all access is usally directed to only the primary server. Whenever maintenance is required on a site's primary server, Web service is moved to the secondary server. Web Site Backups - Each HoloWWW site is backed up nightly to its secondary server. Excess Capacity - We monitor our systems and plan our growth to maintain excess bandwidth, CPU, and disk capacities. Remote CGI - Customer CGI scripts are executed on remote CGI servers.
