dibs has seen this section open 4 times since 18 August. The last time was 27 August. 4 of those were readings where the capacity figure moved and the enrolled count did not, so dibs could not tell whether a seat existed and did not send an alert.

Seats over time

Nothing read since 16 Oct, 11 hours ago. Over about 2 months before that, same seat count, but the status moved and came back, the waitlist moved and came back, the cap moved and came back, and the seat count moved and came back.

Checked 168 of the 1197 hours with hourly history, 14%. No reading was recorded in 1029 hours. dibs had no hourly record before 27 Aug, which is the other 216 of 1413 plotted.40 of 40 enrolled at the newest reading, 11 hours ago, and no seats left. Seats from 18 Aug 20:40 to 16 Oct 16:42, 40 to 40. Checks are not continuous monitoring. Changes between checks may be missed.

A dot is a reading where something moved: the seat count, the status, or the waitlist. Flat between dots joins recorded counts; changes between reads may be missed. The line starts when dibs first saw this section rather than reaching back before it existed. The last one is the last time dibs read this section, moved or not, and that was 11 hours ago. It is where the line stops, not where the count is now.

How readings and alerts work

Dated seat counts can be available even when hourly check history is missing. Gaps do not show whether seats changed between observations.

Seat counts show the last successful read, not live availability. Refreshes can be delayed by request limits or upstream interruptions. Watched sections receive priority, but an hourly update for every section is not guaranteed.

The registrar can change a seat count between our checks. Alerts depend on dibs detecting an opening and completing delivery; a quiet watch does not prove that no seat opened. Check the registrar before enrolling.
