Compute Instance Terminated w/o Warning

My E2.Micro instance, which had been running well for a year, was terminated suddenly without any warning yesterday, along with its boot volume, meaning I cannot even recreate an instance while keeping the data. I understand that I'm using the free tier, but this type of thing should not be happening randomly. I cannot find any reason for why it might have occurred. Is there any way to recover the boot volume at least?

My issue seems to be similar to https://community.oracle.com/customerconnect/discussion/645480/instance-and-boot-volume-deleted-with-no-notice-and-no-explanation and https://community.oracle.com/customerconnect/discussion/645704/why-my-block-storage-terminated-free-tier so could there have been an issue sometime in the past few days that could've caused sudden termination of instances for multiple people?
