Looks like some OS files are corrupted causing network not to come up.
Please note, all of user data is safe.
This is going to take quite some time to repair.
We will keep posting updates as we proceed.
We have managed to recover the server. All services are up and running fine now.
This is a rare problem we have come across and will sure work on ways for faster recovery next time if it happens (we hope not).
we apologize for the inconvenience caused.
