There is a DDOs coming on Win6, it is not the typical high traffic or high packets type, but many many requests, we are working to block the bad requests.
If by any chance we should block a legitimate request we will unblock it with a ticket within 24 hours.
Win6 is running with a lot of network filtering right now which has a bit of impact, if I were basing on 100% scale I'd say it is around 85% 'healthy' now, however sometimes even with mitigation we have done the attacks do increase and hurt it some. We will continue to keep an eye on it today and block more as they come.
I have tweaked the filtering a bit to block some larger blocks, it means in a few regions of the US some major cable companies clients (about 1000 total) won't be able to visit.
We hope to be able to lift this ban within the week, but if required it will stay. The main cause of this is trojan infected computer networks that are used by 3rd parties to launch such attacks.
Still seeing some attacks coming in, so filtering is still in place, we are offering moves to the largest network users(3 users 4 domains) which will help with the filters, and we are offering moves to others that inquire as well.
We only got a reply from one of the users yesterday and that site was promptly moved, and some other clients that requested were moved. Attack is still coming in a bit(but is down some from yesterday) and filters still up at this time.
