What cause of network issue?

Today we got a problem with public network resources on one of our droplet. Or, exactly this is a network problem at all. (droplet region is NYC1)

All services work stable inside: they are working and accessible from the localhost. Nothing changed from the last weekend: local droplet’s routing, firewall rules are the same.

The main problem, that network interface can’t up.

ifup eth0
RTNETLINK answers: File exists
Failed to bring up eth0.

Configs:

cat /etc/udev/rules.d/70-persistent-net.rules
SYSBSYSTEM=="net", ACTION=="add", DRIVERS="?*", ATTR{ADDRESS}='<censored>', NAME="eth0"

Interfaces:

ip link
1. lo: ...
2. eth0: ... state DOWN 

Routes:

ip route
default via <censored> dev eth0 onlink linkdown
10.10.0.0/16 dev eth0 proto kernel scope link src 10.0.0.5

Interfaces config:

cat /etc/network/interfaces.d/50-cloud-init.cfg
auto lo
iface lo inet loopback
  dns-nameservers 8.8.8.8 8.8.4.4

auto eth0
iface eth0 inet static
  address <censored>
  gateway <censored>
  netmask 255.255.240.0

iface eth0 inet static
  address 10.10.0.5
  netmask 255.255.0.0

Can it be caused of this problem: https://status.digitalocean.com/incidents/g1qq8fkqczmc ?
