The signcryption network was down today from 31-Jul-2013 11:49 UTC until 22:24:35 UTC.  Service has been restored.

There are two "backend" servers in secure locations which hold copies of the signcryption keys.  The frontend machines load balance signcryption requests between them automatically.

Last night one of the two backend machines had a hardware failure.  Unfortunately unbeknownst to me the other server had not been participating for the last several days due to a software problem (runit got stuck in a peculiar state), but I had not noticed because the first one had been handling the whole load without problems.

I have added to my monitoring software to let me know immediately when either one of the backend servers stops servicing requests rather than waiting until requests stop being serviced completely.  This is a bit tricky since one of the machines is slower (worse network connection) than the other and the clients will always favor whichever one is responding most quickly, so even under normal circumstances the load is very heavily skewed.

I apologize for the inconvenience.

The printing press heralded the end of the Dark Ages and made the Enlightenment possible, but it took another three centuries before any country managed to put freedom of the press beyond the reach of legislators.  So it may take a while before cryptocurrencies are free of the AML-NSA-KYC surveillance plague.
