Emergency security maintenance

RSVPify is temporarily offline while we apply a critical security update.

A severe vulnerability affecting PHP, the technology underlying a large share of the web, was disclosed today. Out of an abundance of caution, we have taken our platform offline until it can be fully secured.

Your events, registrations and guest data are secure and unaffected. We will restore service as soon as PHP issues the required patches and our security team has confidence in their integrity.
