Server IP blocked on hetzner




Posted by hostfeat, 02-23-2012, 01:40 PM
It's like 48 hours that our server IP has been blocked in hetzner.
We tried to transfer our server to another server but hetzner couldn't give us access to our old server and they do not response to the tickets .. the reason they told about the server blocking is that there was a attack to our server, instead of resolving network issue from their end they blocked my server IP and the point is that they are not going to answer emails.
Any one knows any other way to contact them (I tried phone call- to the number on their website- but the guy didn't help me at all and he told that he can not response on the phone). how to contact to the network department ?

If your server comes under a big enough attack they simply null route your IP thats understandable as their a budget provider and simply dont make enough per server to let bandwidth burn away nor are they a DDoS protection provider...

the blocking is not the main issue as it's reasonable as you told.
but! using the logs they provided we can not prevent the issue, I called lot's of any ddos protection companies : http://www.zenprotection.com
http://www.dosarrest.com
http://www.arbornetworks.com
They all said that I have to know the exact log so they can protect a domain!, here is the log they provided and they just keep saying that I have to wait till the attack goes down:

this irritates me to no end as a hetzner customer.

so, when an attack happens for whatsoever reason (a random pimpleface kid somewhere choosing a random ip to ddos with a small botnet he has under hand etc), our entire server is going to be locked out and we wont be able to get back ?

i would like to hear what hetzner has to say about this.

This is the hetzner answer on the forum :
Quote:
From our experience, 98% of all servers never get in contact with DDOS. Some servers get touched by a DDOS seldom and others get in trouble regularly. We decided to focus on the mainstream of the 98% who never get in touch with DDOS. For the remaining servers, there are well specialised datacenters out there, who handle their requirements very good. We don't have the experience, we don't have the budget, and we don't target this market segment.
