To anyone seeing a Verge article from today reporting a T-Mobile app 'glitch' that affected fewer than 100 customers, that is a separate incident.

Think about 90 GB of data for a moment. That's about two 4K feature-length movies.

Now imagine 90 GB of plain text files, and how enormous a database of customers' personal information that would be. Customers affected might be in the tens or hundreds of thousands.
