It could be a brute-force attack on the CMS, distributed through a botnet.


Any advice on making it useable again?

Blocking the user agent might work in this case - though if it's really a brute-force attack, the attackers could switch to a different user agent, or vary the user agent.

You can also consider putting the side behind a CDN like CloudFlare.
