We lost one of our service discovery nodes in our Asia Pacific Point of Presence due to an instance failure with one of our providers. During the failure the cluster got into a bad state due to a bug in the software. Our functions service is dependent on this being available so it was affected. To fix it we needed to restart the server and the clients on a number of our nodes, which took time in order to do safely. To ensure this doesn’t happen again we are going to apply a fix for the bug that caused the cluster failure.
