We do sincerely apologize for any inconvenience this has caused, and assure you we are making changes, and implementing strict rules to help reduce the affects of attempted attacks on our servers.
We have firewalls, and other security measures in place to help prevent this situation, but its much like a "water-resistant" coat, or shoes. Its not going to help much in a hurricane, or typhoon.
Synfloods are full of useless bogus information and tcp/ip hits. They can last for hours, as we all saw last evening. The technical staff have been working on this, and have set the strict restrictions on the server to reduce the load, to at least keep the sites active. This particular instance lasted for close to an hour.
Even though our firewall, and routing can help to reduce the overall effects, sometimes these types of attacks are so quick and so brutal that it is impossible to prevent them, and only leaves us the option to resolve the issue at hand.
Not long ago, A major switch for some fairly large companies was hit. This caused many a company to be unreachable, including the one of the biggest of all... Microsoft. So you can understand with as much security & protection a company like them has, if they can get hit, anyone can.
I assure you things like this instance are not ignored. We have in the past, and will continue to keep our servers as stable as possible. And compared to others, we do a fairly good job.
