comment The RAID 1 Time machine
A wild guess is that the RAID sda/sdb3 had failed a long time ago, running only on sdb. Now that sdb has failed, perhaps it came back online with only sda?

comment How to connect to an AWS RDS database (deployed in VPC) with an SQL client?
You can make RDS instances that you can connect from the outside world from. You just can't change it. Once private, always private.

comment Setting up SQL server on EC2?
Most of that you can (and should) test. My tentative answer would be: you can resize, but not without reboot. And EBS for mirror/replication: no, it is not atomic, and you can't easily access the backups.

comment Apache/2.4.7 on Ubuntu is hanging with no obvious cause, how can I troubleshoot it?
What does apachctl status say? It can happen that workers are kept busy (status W), either by connections, or even inexplicably...

comment Is a partition necessary when using RAID?
You have that with partitions too, if they max out the space on disk.

comment cloud server performance vs same specification dedicated server?
What does this mean: "the second thing that first bay always slow even if i rendered simple php page"? As for your question, it's kind of too generic. Virtualized servers can be (almost) as fast as dedicated ones, but if on a rented platform, performance is almost always lower, because there are other customers on it.

On (newer) Ubuntu's, restarting ssh that way fails silently and doesn't do anything. Do service ssh restart.

comment Problems with route table with two nics on different subnets
What does your firewall look like (iptables -L -n)? Perhaps your FORWARD rules allows all, but your INPUT rules do not.

comment Server unexpectedly closed network connection
Can you look in /var/log/auth.log to see if your server is brute forced? It can happen SSH has to endure so many attempts, that its rate limiter is activated and you can't get in yourself.

If colo power was good all this time, it would have helped to have a dual PSU server, one of which being fed by the UPS on colo feed A, the other by colo feed B directly.
