The pdf of Necromancer Games' Tome of Horrors has been released for Swords & Wizardry (and also Pathfinder). The download-bandwidth of a 230MB file being downloaded by hundreds of people almost simultaneously ... promptly crashed the servers both at Paizo and Frog God.
The Frog God server is back up again as of 2AM Eastern time, the Paizo server was still being untangled when I talked to Bill Webb this morning.
For anyone who didn't buy the physical book, pdfs will be available for independent purchase soon, but both Paizo and Frog God have temporarily removed their "sale" buttons until the downloads from book-buyers have slowed down a bit. When the feeding frenzy subsides, the sale buttons will show up again at both sites (I don't think Paizo is distributing the S&W downloads, so it's only the FGG server that's relevant to us).
Anyway, for the S&W Tome downloads, the problem is now fixed, but I wanted to let people know the status, and for those who plan on getting the pdf without the book you should be able to do so soon. I do not know the exact definition of "soon" in this context, but ... soon.
