This is a common cyberattack:
Denial-of-service attack - Wikipedia, the free encyclopedia
Our host had a number of these earlier this year. But installing more powerful routers and other equipment will mitigate the problems; the situation has been much better in the past month for us. A good admin team can also harden the servers to reduce the impact as well. If it happens too often -- and nothing can prevent such things entirely -- then someone in the management Cyberstation ought to be looking more into solutions to the problem. Frequent outages mean lost audiences, and perhaps reduced ad income for sites dependent on that for revenue.
I see, for example, that the main Cyberstation site is hosted by GoDaddy (not a good decision based on my experience -- and I live 10 minutes from their main headquarters). They probably should be contacting GD's tech people for assistance, and if they don't get the service they want, take their business elsewhere.
