Data Collection Methodology

Some notes about our data collection.

RSSAC-002

Our RSSAC-002 statistics are known to sometimes be slightly under their actual values. They are complete on normal days, but they undercount during burst periods, such as during a denial-of-service attack.

As of 2016-06-13 we have been generating RSSAC-002v3-format data.

We publish RSSAC-002 data two days after collection completes.

Days are midnight-to-midnight, UTC timezone.
