Our maintenance schedule is essential to ensure the functionality, security, and reliability of REDCap. This includes:

• Routine Monthly Maintenance: Performed on the last Thursday of each month from 4:00–6:00 PM for security patches and bug fixes. Both the REDCap Production and Development systems are unavailable during this time.
• Biannual REDCap Version Upgrades: Conducted during the same 4:00–6:00 PM window, replacing the routine monthly maintenance for that period. Both systems are unavailable during these upgrades.
• Annual Server Updates: Conducted in two phases—one month for the Development system (no participant disruption) and the following month for the Production system. These updates, in addition to routine monthly maintenance, are scheduled on Thursdays from 4:00–7:00 PM. Performed annually, specific dates may vary.
• Emergency Upgrades: Occasionally required for critical bug fixes or urgent security issues.

These updates are critical to maintaining REDCap’s functionality, safeguarding data security, and ensuring HIPAA compliance, all of which are essential for supporting research activities.

Please Note: Adjustments to this schedule may be made when holidays or unforeseen circumstances require changes.
