DDOS Attack on Webhosting - Priorweb
Our webhost is currently experiencing a DDOS attack (Distributed Denial of Service) and they are doing everything to keep Madshrimps running smoothly.

Traffic spiked towards 74Mbit yesterday and today we're still having slow downs from time to time. Let's hope this will all be resolved quickly.

Good work from Priorweb for tracking down the problem and working towards a solution :super:

Dutch version
Dear customers,

Since Tuesday 20 December has been the web server vector the aim of DoS-attack (denial or service). This means that a someone large number of sends applications to the server, with the aim the server or of overloading network.
The cause of the attack lies at a dispuut between the attacker and a customer site which is leaped about on vector.
By the scope of this attack there also delays can appear for other servers in our network.

20:07 - The server where the attack was on targeted, has been found. The server is blocked temporarily so that the movement no longer arrives on network. All servers excluded vector are online
