I got an email from them which said:
"""
Hi!
You’re recieving this email because your organization [...] has Fly Apps with one or more Fly Machines deployed using an A100 40GB PCIe GPU in [...]:
[...]
As part of the process of deprecating Fly.io GPUs, we are shrinking our GPU footprint and are will no longer be offering GPU-enabled machines of this model. We will continue to host these workloads until May 31st, 2026, after which they will be destroyed. Please take any necessary actions to migrate these workloads or preserve their associated data before this time.
For the near-term (at least through to the previously announced Fly GPU deprecation date of of July 31st, 2026), we are still offering A100 80GB GPU-enabled machines that may be compatible with your workloads, subject to available capacity.
[...]
"""
The website has very limited information about why they're doing this, especially since they have many blog posts about their GPU support and why it's great and all that.
