# What does [Edit removed during grace period] mean?

I asked a question a couple of days ago and today I saw that it was edited by some user.

When I clicked on the Revisions, instead of the revision, I saw this:

[Edit removed during grace period]

I've never seen this before. What does it mean?

• I edited your question, replacing "his" by "their". Then I edited again, replacing "their" back by "his". You can see the effect in the revision history. – user147263 Jan 12 '15 at 18:27
• As with many things concerning the underlying architecture, see MSE. – user642796 Jan 12 '15 at 18:35
