I am told that the IF Archive may be offline for some of this afternoon, due to emergency power-line repairs on CMU campus.
(Yes, it’s on a UPS. Is every router and network switch between the Archive box and the outside world on a UPS? Probably. Will every one of them work for the expected one hour of downtime? Maybe. Will the downtime be longer than expected? Who knows.)
If you have urgent need of Archive services, please look at the mirror URLs listed at ifarchive.org/ and bookmark a couple.
