Data in the tables and hosts version distribution is updated every 30 minutes, data in the charts is updated daily around 3:00AM UTC.
"Active Hosts" are obtained from the local hostdb of SiaStats node.
"Used storage" corresponds to online hosts irrespective of their setup accepting or now new contracts. "Total Storage" corresponds exclusively to
online hosts that are also accepting new contracts.
A customization in the code of Sia was introduced on January 11th, 2018 to allow many more hosts scans in the same time (Thanks @Sanasol from SiaHub for the help).
Previously Sia could neither check all the current hosts in the database (resulting in hosts disconnected long ago still being included) nor every
new hosts being included (resulting in undresampled network storage). For this reason, data prior to that date will not be totally accurate. This has been refelected with plotted
lines in the charts.
