What happens if I close browser while upgrading Discourse?

Will close browser or disconnect from Internet cause any problem?

No, it does not matter, you will no longer see the progress but that is it. The upgrade is not interrupted since it happens server side.

Thanks!
Always wondered too, but never wanted to test it myself!
