We have been using your system to track some of our customers flight. However lately we stopped getting alert notification from your site.
I was checked the Recently Delivered Alerts in the Notification section of My Alerts. I saw that all the last alert posts are failed. According to information it only says -

Could you please give us a bit more information? We have no clue why all of a sudden it stop receiving alerts.
Thanks and kind regards.
