In case you were one of the lucky ones able to snag a free account in the olden days, the terms have changed. Instead of 4 CPU and 24 RAM that you were free to whack up amongst 1-4 VPS, now you got 2 CPU and 12 GB RAM, so either one dual-core VPS or two single-core. If you keep using the old setup beyond a certain date (can't be bothered to look up when that is) you'll get billed; at reasonable rates, I'm sure.

If I'm reading this correctly, the block volume storage allotment hasn't changed, but their whole setup is hella confusing, so might be off on that.

Was really a matter of days when they was gonna axe the thing, they fired half a planet's worth of workers, I'm amazed they left even this much.
