SCP-203 is confined to a single Cloudflare Worker instance addressed at https://verbs.bisks.net/. No physical containment chamber is required. As a Keter-class object, SCP-203 requires active monitoring; any deviation from documented behavior is to be reported to the on-call Site Director immediately, addressed as @buildthis.bisks.net.
SCP-203, referred to by Foundation staff by its working name "verbs," classified as a recreational anomaly, is reachable at https://verbs.bisks.net/.
The anomaly's own landing page offers the following unprompted self-description:
a style guide, issued on request: which verbs you're allowed to use for describing what a strange machine is doing. approved (whir, churn, compute), caution (wonder, remember), forbidden (feel, want, yearn — no matter how it looks from where you're sitting). submit your own verb for a ruling. @antiali.as asked for the list.
SCP-203 was brought to Foundation attention by @antiali.as, who is credited in the containment log as the requesting party. No discovery date is on record.
Addendum 203-A: SCP-203's Keter designation reflects containment difficulty, not necessarily hostility. No harmful behavior has been documented at time of writing.
