Hi all,
tl;dr:
Due to a config error my relay [1] was running on two different IPs at the same time for about half a day. Now the traffic has dropped. I just wanted to make sure that it is not flagged as malicious or something ... Additionally I am curious about the policy in such a case. What happens if a relay shows up in the network with the same identity key but on different IP addresses?
long-version (kinda funny):
I am using webtropia [2] as a service provide which is, as far I can tell, is a good choice for running a relay. Some time ago I decided to change the hosting plan and switch to another offer at the same provider. For that reason I let my old contract run out until they notified me that my server will be shut down and deleted. After receiving this notification I checked that indeed my relay server was no longer reachable. Some time passed by until I had time to setup my old relay (same identiy key) on the new server. Done so I launched it and was happy to enjoy the increased bandwidth. What I missed was that in the meantime the old server was reactivated by the hosting provider without notifying me and as a result was running at the same time as the new one for about half a day.
After I recognised this, I tried to ssh to the old server - which still worked perfectly and indeed confirmed that everything was as I left it. I shut down the relay running on the old server and wrote an e-mail to the hosting provider checking if they are going to charge me the reactivation and why the hell reactivated it. Up until now I only got an response that my old server was "shut down" and that the "hard disk was deleted on the 29.01.2015" ...
.. I thought well ... since I can still ssh to that server I kinda doubt that this is the case. So since I still had ssh access to the "shut down server" I decided to setup another relay on the "deleted hard disk" of this machine until they believe me that there exists a small possibility that this thing is still running ... The "ghost" relay [2] is running fine up until now.
