Bit Tally

RANDOM.ORG is a true random number service that generates randomness via atmospheric noise. This page shows how many random bits the service has generated throughout its existence. The figures are updated roughly once per minute.

Service began on:Thursday, 22 October 1998 at 19:52:27 UTC
Today's date:Tuesday, 30 June 2015 at 09:59:28 UTC
Total time operational:526,572,421 seconds
Total randomness generated:2,023,288,896,478 bits (approx. 235.5 GiB)
Equivalent to:371.1 CD-ROMs or 51.2 DVD-ROMs
Average speed:3,842 bits/second†

†The average speed is calculated since the service began (i.e., since 1998). The figure does not reflect the generator's maximum speed but rather its effective speed, which is based on demand, over a long period.
