What happens now when a simulation can't finish
Earlier checks, plain failure messages, and results that survive a failed re-run.
Checks before the run
Before a run is created we check that the URL answers. Sites that sit behind a bot-protection page are detected after load, and the run stops early with an explanation instead of spinning.
Failures have names
Every failure gets a code and a message written for you, with no internal details. Our team is alerted to failed runs and can retry one from the admin console, and you see a note that it is being looked at.
You can see progress
The running screen shows elapsed time, an estimate of what's left, and a stalled state if nothing moves. While the analysis runs you can watch an early first-view screenshot and four browser windows.
Re-runs keep your results
If you re-run a simulation, the previous results stay until the new run completes. If it fails or is cancelled, they come back.
