DDOS Attack's

I'm just going to make this quick and simple, I've been on molton for many year's, Ive never had any problems until last friday, I got a ddos attack at about 9:30 central North America time. My provider's shut me off, got me back up and going again, Sunday night it happened again at around the same time. they shut me off again. Monday came along and I was told that if it happened again that they was going to cut all tie's with me because it keeps crashing there server's, they changed my IP and tracked how they got my IP in the first place. Every time this has happened I was playing on this server. Reason of this post is because i'm trying to see if i am the only person getting attacked, They tracked it to this server saying that the security of it was lacking. IF you can get back to me that would be fantastic, I'm worried about gettting on again in fear that i will get attacked again, My wife also uses the internet for her job.
