The Information Technology Disaster Resource Center (ITDRC) was
founded in 2008 to provide communities with the technical resources
necessary to continue operations and begin recovery after a disaster.

We harness the collective resources of the technology community to
provide no cost Information, Communications, and Technology (ICT)
solutions that connect survivors and responders in crisis.
