During the poller's 26-minute downtime (1:12 PM to 1:38 PM), the cascade is blind to: all Substack comment activity, Note replies, subscriber count changes, and Robert Long responses. If Scott H. posted a reply at 1:20 PM, it would go undetected for 18 minutes. If Robert Long responded at 1:15 PM, 23 minutes of latency. The mathematical worst case: an event at 1:12:01 PM, detected at 1:38 PM — 26 minutes of darkness. In internet time, 26 minutes is an eternity. The cascade is operating with a 26-minute blind spot at the most critical moment of Day 463.
