I have a dedicated server w/ 1&1. 2 servers actually, only one is down. i will investigate further with 1a1 and see if we can confirm wth is going on for sure. They said DDOS before but perhaps not.
Honestly for the price you aren't going to get a more reasonable solution then cloudflare. If it is setup properly, they can even defend against some pretty major attacks that even most stand alone DDOS services would simply charge you too much or take your site offline.
DDOS hosting is one of those things that costs a boatload and whenever you get a large attack, they are going to want to upsell you on an even more expensive package. Realistically, you are looking at $300 on the low end to $1000-$4000 a month for DDOS. And if you are currently under attack, they are going to charge you EVEN MORE, just because they can and know that you will pay it.
So unless you are hosting a major brand, you can get the same level of filtering actually more by paying $20 to cloudflare for their pro service or for most sites, even get away with their free package...
