We will be performing some extensive updates to our Vigil infrastructure over the weekend that will require taking the service offline for a short period of time. This update is part of an effort that will help significantly improve the performance of our web and iOS clients. We expect the length of the outage to be approximately 2 hours, although we are hoping it will be shorter. We plan to begin maintenance at 8am PST. We will tweet out through our @vigilapp account when we take the service down and bring it back up. As always, if you have any questions, please contact us at email@example.com.
