连续两天两次，然后没理，过了一会就自己恢复了。
然后昨天：
Hello,
The physical host that your Linode currently resides on became unresponsive to our monitoring and required an emergency reboot. The host is back online and Linodes will be returning to their last state (booted or shutdown) shortly. However in order to protect your Linode from any further downtime, we have scheduled an emergency migration to a different host in the Fremont facility.
Your Linode has been entered into a migration queue and it will be moved to its new host shortly. Your Linode will be gracefully powered down, migrated to its new host, and then returned to its last state; you will not be required to manually power on your Linode. You can monitor your position in the migration queue in the Linode Manager. The migration process can take up to 2-3 minutes per GB.
Please accept our sincere apologies for any inconvenience this may have caused you. Should you have any questions or concerns regarding this issue, please do not hesitate to reply to this support ticket.
