While at a meeting during the week (Oct. 2-4, 2015), I noticed that the Forum was suddenly out of service. Further explorations showed that several other websites and the DSSR manual were all not accessible. I suspected a power failure that had brought down the two servers (named x3dna and dssr) under my desk.
When I came to office this morning, I immediately found that both of my machines were off. Simply switching them on, and everything is back to normal. This is the first power failure experience after the x3dna and dssr servers have been put into service. Yet, it does remind me to have a backup plan.
Sorry for the inconvenience the shutdown may have caused.
