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:Wednesday, 18 September 2019 at 02:47:18 UTC
Total time operational:659,688,891 seconds
Total randomness generated:1,014,033,219,055 bits (approx. 118.0 GiB)
Equivalent to:186.0 CD-ROMs or 25.7 DVD-ROMs
Average speed:1,537 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.
