Apparently they only sent 3 notification Emails, which a large number of their customers are reporting they never received. No one at InfluxData thought to do a scream test or even check the traffic levels to the region before deleting the data.
This is insane. The data is gone??? Why would you delete the instances? Think about it, they made a terrible decision to just stop services for no other reason than cost cutting. Customers were not fully aware and they randomly deleted everything. While still a horrible solution, they could have just shutdown the instances and had the data available for a period while they assessed the impact but no, they just went straight to delete. That is the most extreme example of incompetence that I’ve seen in a while.
