VPS is online and responding. If the files are not within the device they have unfortunately been lost and are non-restorable.
Many of our customers have faced this issue, we have placed a 20TB+ nas cloud system to take datacenter wide backups now to prevent such dataloss in the future.
Some VPS were not effected, however if your VPS was created as fresh the data is unfortunately unable to be restored. The data was fully wiped and forcefully removed.
If there's anything else I can assist you with please let me know. We greatly appreciate your understanding during this large inconvenience.
