We are seeing the following error on our Windows GitHub Actions builds:

2025-04-07T21:30:54.0363865Z curl: (28) Failed to connect to www.cygwin.com port 443 after 21052 ms: Could not connect to server

I confirmed that this is not caused by any change on our end by pushing an empty commit to a branch that had a successful run last week. The GHA build triggered by my push failed.

Successful build last week:
