In the past week, my server was down couple times due to massive attacks from unknown sources targeting liewcf.com (this blog).
The malicious traffic caused high server load (load spikes) and brought down the server. Restarted web services didn’t help.
That was very frustrating. Website uptime is essential for a full-time blogger, just like how important is the car for a taxi driver.
Website down = No traffic = No $$$
I spent hours and hours sitting in front computer to monitor the server load. Mood went down with the server…
Here I have to praise the support of my hosting provider — Liquidweb.
In order to monitor my server for load spikes that happen randomly, server admins are assigned for 24/7 close monitoring. *thumbs up*
In the end, the server admin blacklisted the IP addresses to return the server to normal stage.
So far, the server performance is good now. There are still some load spikes now and then, but eventually they go down before bringing down the server again.
