To be clear, disk corruption can happen anywhere due to many reasons, in particular when VM disks map to local disks on an hypervisor, which gives you fast SSDs without network latency. Probably that the resize command had an issue and corrupted the image on disk. Then there's not much that can done aside from restoring from a backup. Having had backups enabled on the droplets, they would in all likelihood not have been corrupted since backups with DigitalOcean are stored offsite. In such case they could have been used to restore the droplet.
In some extreme cases, a concert of bad luck may coincides to ruin things despite multiple levels of redundancies. But that's extremely rare, especially nowadays. However DO is much larger now than it used to be, so the odds of hearing about extreme accidents increase.
