legend

project site -- home

project site is an url. The href is the href for the site in the list of mirrors, usually the root of the mirrored file tree. The text is the site of that url.

home (represented by the @-symbol) is an url pointing to the document root of the site. This pointer is useful if the project site url is invalid, possibly because the mirror site moved the archive.

type

Indicates the type (ftp or http) of the project site and home urls.

mirror age, daily stats

The mirror age is based upon the last successful probe.

Once a day the status of a mirror site is determined. The status (represented by a colored block) is appended to the right of the status history (right is recent). More precise, the status block is appended if the last status block was appended 24 (or more) hours ago.

The status of a mirror depends on its age and a few configuration parameters :

status	age
	this project		in general
	min	max	min	max
fresh	0	6h + 1h	0	min_sync + max_poll
oldish	6h + 1h	12h + 1h	min_sync + max_poll	max_sync + max_poll
old	12h + 1h	∞	max_sync + max_poll	∞
bad	the site or mirror tree was never found

last probe, probe stats

Last probe indicates when the last successful probe was made. Probe stats gives the probe history (right is recent). A probe is either a success or a failure.

last stat

Last stat gives the status of the last probe.
