Content is getting cached

Hello All,

I'm troubleshooting a situation where content/state is getting cached somewhere and I'm trying to figure out where.

We're a county agency on the government cloud. Over the last week, our users are encountering these scenarios:

1. User A edits a Word doc.

2. They check their changes in.

3. The system continues to show them that they have the document checked out. 

4. User B sees that the document was checked in recently.

1. User A (Full Privileges) deletes a Subsite.

2. Subsite is still visible in Navigation

3. Clicking on the subsite link gives a 404 error

4. User B does NOT see the subsite in the navigation

I had both of these situations yesterday.

Question: Does Sharepoint (in the government cloud) do any caching? Can that be disabled?

Or is the problem elsewhere?

Any insights are appreciated.
