Most people on there probably already know about it, but just in case they haven't heard the news: Cloudfare had a massive security vulnerability that leaked customer information which was then indexed by search engines. It's been patched, but Cloudfare's reach is quite far.
There's a Github repository dedicated to the exposed sites and their status. On the list is DigitalOcean, which myself and several other people here use. While there hasn't been any reported DigitalOcean customer data leaked, it would still be a good idea to change passwords or other security details.
Here is the link to the Github.
EDIT: If you post on Reddit, it was hit as well. Change your password there, too!
