[Witness Failover] Public Released Of STEEM Witness Failover Node.js Script
Issue
If you are a Steem witness, you know how important it is to ensure that your server is constantly online and producing. However, sometimes shit happens and there is nothing you can do about that ... besides being prepared.
Solution
For these reasons, I created this Witness Failover script because some of the other ones out there already have become outdated for whatever reason. The script will run constantly inside a docker container watching the total_missed blocks for a witness. When they total_missed blocks exceeds the threshold, the backup witness will be activated and a SMS message will be sent to the owner.
Summary
Hopefully by releasing this script other users will be able to configure their own witness failover setup. This will help the Steem network to remain stable and profitable for many years to come.
