instapaper.com seems to be hosted @ AWS

Which DB at AWS:

https://aws.amazon.com/products/databases/

Also shouldn't AWS warn them that this was about to happen?

Edit 1:

DynamoDB says: "There is no practical limit on a table's size. Tables are unconstrained in terms of the number of items or the number of bytes."

The SQL databases say this: "The Amazon Aurora engine will automatically grow the size of your database volume as your database storage needs grow, up to a maximum of 64 TB or a maximum you define. The MySQL, MariaDB, Oracle, and PostgreSQL engines allow you to provision up to 6 TB of storage on-the-fly with zero downtime."

So they either hit 64TB or 6TB of data I assume?

EDIT 2:

According to this they are MySQL based: https://medium.com/making-instapaper/rebuilding-instapaper-s...

Think you need to set up CloudWatch to get alerts.

And CloudWatch is free for RDS at 5-minute collection intervals which is more than adequate for alerting on things such as "Am I about to hit the space limit on my database?"

They could be on aurora though since many people just consider it to be mysql. It's a pretty painless migration from mysql as long as you are 5.6 or below. You can just replicate over to it live.
