I run this site on a VPS. I recently had some problems because there was no log management configured for SQL and a harmless warning completely filled the storage. The irony was that, as the storage filled, the more applications failed and the more errors were generated, so it totally snowballed.

In the following week I had two portable devices start to display odd behaviour too. Turns out both of them were also short of storage. Several apps on one iOS device had apparently cached gigs of data that could only be removed by uninstalling and reinstalling the app. This feels like a problem we solved decades ago but then developers started relying on increasing storage capacity instead and stop caring.
