Hi, yesterday I set up a WordPress server with 1GB Droplet for WordPress with 1GB separate droplet for Mysql Database. Today I after I logged in to control panel I saw a sudden Spike in CPU and Disk IO and A sudden Fall in Ram after that. I checked my website its down server was frozen, I tried to ssh to the server and tried to restart the apache, nothing worked so I had to restart the server from control panel
this is the apache /var/log/apache2/error.log ->https://pastebin.com/7ZFx2d3T and this is the screenshot of the graphs -> https://drive.google.com/open?id=1ALH9rSALrfHD_gP48P248AXKUGFxt6Vi
(Logs time zone and graph time zones are different )

Hello,
It looks like that there was a spike in your traffic which caused the sudden CPU load. What I could suggest is:
- Make sure to add enough resources to your Droplet, you could run a stress test in order to be able to determine how many visitors your site could handle at once:

-
Also make sure to optimize your Wordpress website, for example, delete all plugins that are not absolutely necessary, install a caching plugin and maybe enable a CDN
-
Check your logs and make sure that there was no malicious traffic towards your site, you could, for example, use this script here to summarize your access logs.
