Hey everyone. I'm still pretty new to Terraform and managing our AWS infra. We've been running Terraform Cloud with the remote backend for a few months.
Lately, we've had a couple of brief network timeouts during `terraform apply`. After the blip, the state file seems to get corrupted or out of sync. The UI shows operations as "completed," but the actual resources are half-created or stuck. The logs are confusing, too.
What we see in the run:
```
Error: error acquiring state lock: HTTP code 408
...
```
But then later, a new plan acts like the failed resources don't exist at all 😨. We have to manually check AWS and sometimes run `terraform import` to fix it.
Has anyone else run into this? Is there a best practice to make the remote backend more resilient to network hiccups? Are we just using it wrong?
Oof, yes, that's a familiar pain point. That 408 during the state lock is the worst - it leaves everything in limbo.
One thing that helped us was tightening up our `-parallelism` setting on larger applies, and using `-target` more aggressively to break changes into smaller batches. It doesn't prevent the blip, but it limits the blast radius when one happens. Means more runs, but less cleanup.
Also, have you looked at setting up a `post-apply` webhook to a simple health check? We rigged one to ping our status page, and if it fails, it at least flags the run for manual review before we move on. Might not solve the import problem, but it catches the "UI says done but it's not" scenario faster.

The webhook idea is smart for detection, but it's still reactive. Smaller applies with `-target` help, but you're just moving the problem around.
You need to treat the remote backend like any other external dependency - assume it can fail. We bake idempotency checks into the apply step itself. A simple script after the lock release that does a quick `terraform refresh` and compares the output with the expected state can flag a mismatch before the run is marked complete. Adds a few seconds, but prevents the "UI says done" scenario entirely.
If your network is that flaky, you might want to look at the backend configuration itself. Are you using the default HTTP retry settings? They might not be aggressive enough for your specific latency.
Integration is not a project, it's a lifestyle.
Oh, the classic 408 lock timeout. Welcome to the special hell where your network hiccups become a multi-hour manual audit.
The "best practice" you're looking for is often just admitting the remote backend is a single point of failure they don't advertise prominently. Making it "more resilient" usually means wrapping it in so much custom logic - like the refresh checks others mentioned - that you're basically building your own state manager on top of the one you're paying for.
You're not using it wrong. It's using you. The real question is whether the convenience is worth paying for a service that still forces you to write scripts to verify its basic correctness after a common network event. Have you calculated the time spent on imports and manual checks against just running the OSS version with an S3 backend and proper DynamoDB locking? The cost delta might surprise you.
