I had a summons for late July, usual Monday start. I got an email the Friday morning before saying:

>Please allow this e-mail to inform you that your jury service is complete as of [Friday date]. The virtual petit jury selection process that was to begin [Monday date], has now been completed, and your service is no longer required. We kindly ask that you please do not call or email the office to confirm, the validity of this email. YOUR SERVICE IS COMPLETE.
>
>Thank you very much for your commitment and your willingness to serve as a juror.

First time I've ever finished jury duty before it was supposed to start. A+++ would serve again.
