Trends

How the synthetic window moved: how busy it was, how often briefings ran slow, and how often a stored copy was found. These describe the past. They are not forecasts.

This page always uses the whole synthetic window: about 76 hours, Mon 05 Jan 00:01 UTC to Thu 08 Jan 04:25 UTC (1,200 synthetic requests), whatever time range is chosen on other pages. Dates are synthetic.

Hour of the day

Synthetic

All days together, by hour in UTC. Hours at least 1.5 times as busy as the typical hour are marked: 12:00–18:00, 20:00–23:00 UTC. The quieter hours were 00:00–12:00, 18:00–20:00, 23:00–24:00 UTC. This describes this window only.

The slowest three-hour stretch

Synthetic

Tue 02:00 to 05:00 UTC: the middle briefing took 8.5 s across 16 briefings. With this few briefings the figure could just be random variation.

One stretch is one observation. It says nothing about why, and one bad stretch is not a trend.

What this page cannot tell you

Not measured

Weekly and seasonal patterns Not measured

The window is about 3.2 days, so no weekly or seasonal pattern can be seen.

What would measure it: Real records over several weeks and seasons.

A forecast of what comes next Not measured

These figures describe what already happened. Nothing here forecasts volume or speed.

What would measure it: A forecasting method tested on real records, which does not exist yet.

Engineering details: how the blocks are made

Blocks are 6 hours, on UTC clock boundaries. A request belongs to the block its start time falls in. "Over 8 seconds" and the middle time use only briefings with a recorded time. The share of stored copies found is stored-copy checks that found a copy over all checks made, for requests with a record.

An hour is "busy" when its request count over the whole window is at least 1.5 times the median hourly count. It is computed from the data, not set by hand.
