Back in the early 2000's, I was involved with bringing up, diagnostics, and bench-marking large-scale supercomputers. Would occasionally tell management, with a day or two of notice, when would be a good time to schedule maintenance, rather than attempting to run customer's application codes. Back then, I was using spaceweather.com, a somewhat simplified and sensationalized version of the spaceweather.gov.

On days when I knew what was coming, it was (almost) fun watching ECC single-bit error counters ticking up across the O(100k) nodes...like watching popcorn pop in a hot pan.
