We have been at a very sustained DDOS for the past week but managed to mitigate it! AND I do agree with your thoughts on who is doing it and it really does make a lot of sense to attack the top 3 sites, competing with their 3 products! So low class!!
As an endorsed company I'm a tad disappointed with you folks pointing fingers at another company. If I think it's the same company all the organizations are claiming it is "BetcoinTM" I can assure you folks your probably wrong. The gentleman is pure 100% class and is a true asset to bitcoin gambling. I think instead of pointing directions at other companies we could use the time, resources, and energy on adapting away to defeat these dos attacks so players can continue on doing what they enjoy doing. Dos attacks are not uncommon for larger companies and with proper backup plans like mirror backup sites this can help defeat the purpose of the attack and that is your player base.
I would suggest you to stop schilling. How much are they paying you?
