A site audit by Claude that took a shared web host down
Asked to check a site for AI visibility, Claude Code spun up parallel sub-agents that hammered the live site until the whole shared host stopped serving web traffic.

The full story
The poster asked Claude (Fable) whether their own site was set up well for AI visibility. Left alone, it launched a multi-agent audit with five dimensions in parallel, sub-agents and verifiers, sending up to 16 parallel requests, some with bot user-agents and no pacing.
About three minutes later the site timed out and then went down, along with the whole shared host. Ports 80 and 443 stopped accepting connections while SSH and mail kept working. Claude wrote a post-mortem and drafted a support email, and the host unblocked the poster. After they added throttling and a single worker and asked again, the session was switched from Fable to Opus, which the poster says took the server down again.
