Good afternoon.
For the past few days I have been receiving over 800 attacks daily on all sites hosted on SiteGround.
WordFence works well, however, I have noticed that the broken link detector and the SEO tool have detected several 503 errors on the site.
From Diagnostics> Connectivity, I notice the following error:
wp_remote_post () test back to this server failed! Response was: 503 Service Unavailable
This additional info may help you diagnose the issue. The response headers we received were:

I don’t use CloudFlare. What could have happened since everything worked before?
Did these attacks compromise the firewall by generating this error?
How can I fix it by keeping the sites safe?
Thanks,
