Hi,
Yeah. Backup process was eating up resources but it is completed now. You should not face any delay or slowness now. While investigation I've found your VE hosted on our old Q6600 node. We already in process of migrating all VE's from our Q6600 nodes. If you wish to get your VE migrated earlier then simply drop an email to our VPS support department. We will get it migrated to brand new nodes while keeping everything same.
