Wordpress is notorious for causing excessive load, and is one of the leading causes of a load suspension.
The spike on the below chart was your WP site hogging an absurd amount of both CPU and memory. The CPU usage is what got you suspended...you used 11348 in under 2 hours, the limit is only 10000 for an entire 24 hours. Either your site is broken, or you have a plugin or something installed that is way too heavy to host here (woocommerce, elementor, and wordfence are the three worst offenders, but others can also definitely cause this issue).
You can take a look at this page on Wordpress for information on how to reduce its load as well as alternatives to WP: https://wiki.helionet.org/misc/wordpress
Please fix it quickly.
