To be honest, I highly doubt it is due to a security attack as they claim. It has been down for 3 days now. This has been happening only now not anytime in the past. I recaptcha and another security plugin in place.
I feel this only due to unethical practices of overloading one server instance with higher number of webiste and choking on it.
Leaving it so long without any resolution, emails or any official acknowledgment. Is straight denial of service in my eye.
Let them play their game till time permits.
