I just update the system through yum update command.
After that, I reboot the VPS, then, lost the connection to this VPS and web site.
- Can not access the web site on it from browser.
- Can not access the VPS through ssh
- Can not access the VPS through Serial Console.
I create a ticket on servermania support. The support team replied in 20 minutes.
After two conversation between Andrew and me.
He told me that the problem is:
The yum update had broken the iprouting on the OS which caused the venet to not come up.
He fixed the problem and the VPs is back now.
Now the VPS powered by CentoOS 6.5.
