All servers in the 220.127.116.11/24 subnet are currently experiencing packet loss – even those in different racks, so this appears to be a routing issue with our upstream provider.
We have logged a ticket with them and updates will follow shortly.
Update: This turned out to be a client under a large DDoS attack, his account has now been closed due to suspected illegal activity.
xn23 is currently down and we are getting a KVM attached.
Update: There appears to be a problem with the RAID array and its completely locked up, have requested a reboot.
Update2: After a power cycle we can confirm the RAID array is fine, so further investigation will be carried out to find out why this occured.
If you have a VPS on xn23 and its currently offline, please be patient and it will be restarted automatically.
