I've been with SDF for years. I cut my Unix teeth on their servers. They're a fantastic host and I am very impressed that their "Meta Array" coped with the influx of HN traffic without skipping a beat. I've been periodically checking the site, with an empty cache, while this link was on the HN front page and page delivery was consistently sub-1s. Theirs is extremely cheap hosting too. I have nothing but praise for the SDF.
