+## How to handle certificate expiry
+
+When CI starts spuriously failing, it is usually caused by the certificates inside `src/tests/vertification_real_world` reaching their max issuance lifetime and becoming expired. While most
+of our tested platforms are able to handle this better by mocking out the verification time, some can't. At the time of writing these are:
+- Android ([1](https://github.com/rustls/rustls-platform-verifier/issues/59), [2](https://github.com/rustls/rustls-platform-verifier/issues/183))
+- Windows ([1](https://github.com/rustls/rustls-platform-verifier/issues/117))
+
+The other case that can cause failures (much less often) is the mock certificates expiring. Due to platform verifier security restrictions, we can't place absurdly high/unlimited expiry dates
+on our mock CA and the certificates issued by it. As such, they will expire about every 2 years and need updated by hand.
+
+Thankfully, updating these has become easy:
+- If the `verification_real_world` tests are failing, do the following:
+    1. Run `cargo run --example update-certs.rs`
+    2. Using your tool of choice, update the hardcoded time in `verification_time` to match the current datetime.
+    3. Commit your changes and push up a fix branch/PR.
+- If the `verification_mock` tests are failing, do the following:
+    1. Run `cd rustls-platform-verifier/src/tests/verification_mock`
+    2. Run `go run ca.go`
+    3. Using your tool of choice, update the hardcoded time in `verification_time` to match the current datetime.
+    4. Commit your changes and push up a fix branch/PR.
