Wait a second.. you consider a provider giving data from your VMs to another random customer a SMALL issue?
Maybe you don't have anything of importance on your VMs, but plenty of people do. That data could contain credit card data, passwords, etc, etc, etc. It is very much a large issue.
Sure. My thoughts don't apply to everyone here, and I certainly can't claim to be unbiased since I like DO so much.
According to DigitalOcean, they stated that this impacts 3% of all machines, only the largest and most expensive servers. None of the smaller plans were leaking data.
I don't know how many credit card numbers were leaked from linode, but I'd guess more than 3%.
Second, if security is important to you, you can use 'dd' to clear the machine yourself before shutting it off. (In fact, good data destruction policies mandate the use of 'shred' et al anyway). On Linode, affected users don't even have a workaround (like this) to avoid information compromise.
