What if the attacker will not stop until you stop. You're an idiot for thinking that way.
There is always a chance that the attacker does not have much time or resources, and is aiming for a quick shutdown of my hosting service. It may be this way since the downtimes are not 24/7.
If it isn't a DoS then it might be just your stuffty network. Either way the easy way out right now is to close it down. You're not going to get anywhere with this constant attack.
The network has never behaved like this before. Before my hosting service, the ISP had at least 99.9% uptime for 2 years. The only outages happened during power outages (therefore it's not their fault). Because of this and the patterns in downtime yesterday, I am suspecting a DoS.
I know I am not going to get anywhere for the next few days, but it could atop. I have invested enough time and coins into this. The business plan did not expire yet.
