I moved several small sites plus one large site to Cloudways back in December. Then, on February 15, 2020 the CPU of the small server spiked to 100% and has stayed at 100% ever since.
This makes no sense for several reasons. 1) The sites were moved exactly as they were at WPEngine where they had no such issues. 2) Cloudways continues to send me alerts “suggesting” that I upgrade my server even though I have turned OFF “Server upgrade suggestions” under CloudwaysBot>Notifications>Settings. 3) I saw that a couple of the sites were getting hit by brute force attacks so I reported the IPs to their hosts, added security plugins to block IPs based on failed logins, changed the name of the wp-admin pages and even turned off xmlrpc to stop these attacks. 4) Although the server shows 100% CPU usage, the details for the apps only show 2.38% CPU usage - how can that be?
Even though they claim to have things in place to mitigate brute force attacks (https://www.cloudways.com/blog/what-is-brute-force-attack/) they certainly are not helping on my little sites.
The whole thing just seems like a scam to get people to buy larger servers and pay Cloudways more money.
