Failed to query the QRBGS database!

*Cumulative statistics is updated once a day.
[2012-05-09 T 23:00+02] Dear users, we'll be doing some performance upgrades over the course of next several days. During this time QRBG service will not be available. Thank you for your understanding.
[2011-07-15 T 02:00+02] Due to network/power outages, QRBG service will probably be down for the next couple of days (until Monday). Our apologies.
[2011-05-27 T 12:00+02] Due to power outages, QRBG service was unavailable for a couple of days (on Tuesday and Thursday). Our apologies. On the bright side, we've used this opportunity to do some upgrades. :-)
[2010-09-27 T 00:00+02] We're running little short on numbers (serving from cache), so we'll be enforcing new download quotas, starting today. You can check your quota under "Quotas" sidebar section while logged in.
[2010-09-09 T 16:00+02] Due to QRBG device malfunction, QRBG service will be unavailable for a few days (let's hope so). Our apologies.
[2010-07-28 T 17:30+02] Due to network malfunction, QRBG service was unavailable for a past few days. Our apologies.
[2010-06-01 T 11:56+02] QRBGS is now available.
[2010-05-31 T 18:00+02] Due to technical issues with part of the equipment, QRBG service will be down until tomorrow noon, 2010-06-01 T 12:00+02. Sorry.
[2010-03-05 T 13:47+01] QRBGS is now available.
[2010-03-05 T 03:00+01] Due to server physical relocation, QRBG service will be down until 2010-03-05 T 14:00+01.
[2008-09-22 T 13:12+01] Due to regular server maintenance QRBG service was down for an hour. Now it's back online. Updated. :-)
[2008-03-14 T 19:30+01]
Mr. Javier Ruiz from the Escuela Técnica Superior de Ingeniéría Informática de la Universidad de la Laguna en Tenerife organized a Pi Day celebration
today at his university. Here is a short blog post
about it (in Spanish). In short, they played approx. Pi minutes of number Pi, with digits downloaded from our service. :-)
Happy Pi Day everyone! :-)

The service is up again! Unfortunately, the QRBG device we had died last week.
Until we buy new a generator, the service will be serving you from its 1 TiB disk cache. For that reason, we're starting to (temporarily) enforce per-user download quota of 1 GiB per day.
[2008-01-08 T 12:30+01] The service will be down for some time, due to technical difficulties with the QRBG hardware. We'll try to resolve these problems as soon as possible; until then, we apologize for the inconvenience...
[2007-11-22] The service (including the web) will be down in period: [2007-11-26T14:00+01, 2007-11-26T20:00+01], due to server maintenance.
[2007-10-15] I'm running some Monte Carlo simulations that require over 1 TiB of random data. So, I apologize for any slow-down you may experience. Simulations will take a couple of days. Enjoy the quantum randomness! :-)
[2007-08-22] For the last several days the QRBG service/server was unavailable, due to a disk failure caused by a heavy thunderstorm last week. The service is now back online. We managed to recover all data, including the users database, so you can continue using the service as usual. Thank you for your understanding and patience.
"The crowd went wild!" :-)
Yesterday, over 1 million hits. Over 80,000 visits. Over 2800 registered users. Over 5GiB of random data downloaded. Over 20,000 user requests served...
Keep on coming.. :-)
[2007-07-19] I was thrilled to see that the QRBGS project has been SlashDotted. And Dugg (or however you spell it :D). Unfortunately, the original text that these sites refer to has been written by the PR department, misinterpreting some facts in the process, and forgetting to run the final version by me. In spite of that, the article inspired quite a bit of interest. I would like to apologise to all the readers who are now busily generating their pseudo-random number databases by rolling dice. :-)
The Service has begun as a result of an attempt to fulfill the scientists' needs for quality random numbers, but has now grown to a global (public) high-quality random numbers service.
Design requirements for our service were:
So far, all these features, except the last one, have been implemented.
And the solution developed tops other currently available random number acquisition methods (including existing Internet services) in at least one of the numbered categories.
To ensure high-quality of the supplied random numbers (true
randomness) and high speed of serving, we have used fast
non-deterministic, stand-alone hardware number generator relying on
photonic emission in semiconductors. The used Quantum Random
Bit Generator was previously developed at Rudjer Boskovic
Institute, in Laboratory for Stochastic Signals and Process
Research (for details, see below).
To achieve high availability of the service, several network access modes are developed, or shall be developed. These include transparent acquisition of random numbers using C/C++ libraries, web services (access over the SOAP protocol), and Mathematica/MATLAB client add-ons.
To enable high security, in future, SSL protocol shall be supported, i.e. all data shall be encrypted, at users request, with user/service certificates.
If you are interested in more details, you can find them in my paper: "Quantum Random Bit Generator Service for Monte Carlo and Other Stochastic Simulations." (download)
Please feel free to register, download the client of your preference (from the Download section) and start using the service!
