If they have a bug that can crash their servers, they likely won't want to publicize the details until it is fully patched. I wouldn't expect that detail for a while.
As an ex CTO having lots of fire fighting experience, I wanna give the honor to the team being able to identify such a user triggered bug in such a short period of time. Hardly anyone would anticipate a single user can trigger a meltdown to the internet!
It reminds me of that ancient joke:
A QA engineer walks into a bar.
He orders a beer. Orders 0 beers. Orders 99999999999 beers. Orders a lizard. Orders -1 beers. Orders a ueicbksjdhd.
First real customer walks in and asks where the bathroom is. The bar bursts into flames, killing everyone.
