yep, did the same for my team at one place "[IMPORTANT] CUSTOMER OUTAGE" (or something similar).
We had a publicly viewable calendar policy. And I couldn't believe the audacity of people in other areas to take it upon themselves to just book over the top of existing meetings because they had decided their meeting was more important. And I'm not talking a group meeting where it's hard to find a gap that works for everyone, these were essentially 1:1 meetings where the organizer was someone with a little more seniority. No polite ask/DM first if it's ok, or a note in the invite to explain. Just see "focus time - no meetings" or something else _they_ deemed not important and they'd schedule it in that block and assume the IC wouldn't challenge their authority.
So had to play them at their own game to give my team their time back. The meeting was as much as an invite to them to challenge my authority as their previous attempts were. Conveniently it worked and nobody would book over my meeting. I do not miss working for larger companies.
