I'm not an expert in internet architecture, but shouldn't a site this important be running on redundant servers? The irony of a tech site going down due to technical issue is making me grin, however. Glad to see it back :)
Really?
Obviously Im a fan of the site, etc, etc, but "important"? On what level?
Im not even sure I'd call Facebook or Twitter important. Banking, yes. Weather warnings, yes. Things like that, sure. But, Im also pretty sure "important" is slightly over egging it for dear HN.
(No offence PG xxxx)
Which is why I have a backup of it in case this happens again.
Imagine Twitter or Facebook being down during Egyptian revolutions.
Up-time for those type of sites is probably important for retention. But not for significant world events. But then again, Twitter kinda proved that even for retention that's not very important given how flaky that used to be.
