These things happen at schools. I don't the stats myself, but thousands of times each year doesn't sound too far off.
But at a place like Cal Tech, when this happens once, the school DROPS THE HAMMER on the student body for a time to try and head it off from happening again. At Princeton, where I went to school and worked, that meant a flood of counselors, town hall meetings in all the dorms, a spate of articles in the papers, etc. Wall to wall discussion to make sure that if you know someone who's struggling, they get some help. This emphasis fades of course, and who knows how effective it really is, but I do know that numbers at the counseling centers would shoot up for a time as students were encouraged and felt comfortable seeking help.
So if you run a school and this happens three times in 3 months, I imagine the administration would be pretty upset and worried.
