UPDATE Sept 9, 12 pm: All OpenTopography systems should now be up. The visualization server may be intermittently unavailable due to residual networking issues caused by the Southern California power outage.
On account of yesterday's southern California power outage, most OpenTopography systems are currently unavailable. The OpenTopography homepage: http://opentopography.org has been restored, but all data access, processing, and related services are currently down. We'll be working with San Diego Supercomputer Center IT support staff to bring servers up and restore full functionality as soon as possible. Thank you for your patience.
