RESOLVED: myopenHAB Networking Issue
Update: Apologies for the long delay, for an undetermined reason, connections were constantly closing prematurely causing a large amount of reconnects and load which contributed to the service being unavailable. The system now appears stable, i have also added an addition backend server to help distribute the load going forward. I will continue to investigate if there is additional tuning we can perform on our load balancers to throttle incoming connections during incidents like this.
It seems that Linode has had another network issue and severed all network connections to our service for a short period of time. Clients are connecting again, but the service will remain slow for the next hour while this happens.
