Re: How is Uptime measured?
An uptime tracker tracks the average uptime of an unlimited amount of days.
A uptime tracker which a webhost uses checks whether a site is online every 30mins and...
if site is online, give the site a good mark
if site is offline, give the site a bad mark
the uptime tracker gets the totals of the marks
so if website has 100 marks and 50 of them are good marks
website gets 50% uptime.
The thing about this system is if, website has had 100% uptime for three months and then becomes offline for five days, the uptime rating will say 83% (estimated). And if website has no downtime since then, the uptime rating will eventually go up and up as website gets more good marks so the uptime will eventually be 90%, or 100% if enough time goes past.
