Question
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

gateway <censored>
netmask 255.255.240.0
iface eth0 inet static
