Actually it sounds quite reasonable. I used to work for a major IT corporation and their SLA didn't amount to much more than that in that particular class of service (i.e. not highly available and/or clustered machines). But they needed a lot more words, to spread the wealth to the legal departments of all parties involved. <tangent> I'm not entirely against such efforts of long uptimes. I strongly believe in efforts to back up rumor with fact, as in the rumor 'FreeBSD is rock-solid'. Actually I believe it is, but I can't prove it beyond talking of my own experience with it. IMHO a lot of so-called fact is actually hear-say or anecdotal, either because the people spreading these 'facts' don't bother to update their info, the info is purely from each sysadmins personal experience and/or because there's a lack of info that is standardised and repeatable. So this web-site's effort, although similar to the Netcraft uptime stats, is quite alright since it's a first step towards getting some numbers. </tangent>
