I've never heard of Vultr until today. Have you used it? Can you tell more about it?
5$ SSD VPS, 768M of Ram instead of 512 at DO, the reason I moved in at first.
The popularity clearly helps DO keeping up with more 1 click apps and other features than Vultr, but they recently made available reserved IPs and Object Storage, so they continue to be a good alternative to DO.
So far it's been working well and support was very responsive on the one occasion when I needed their help.
