70All mirrors must be synchronized every four hours, starting at midnight in your
71local time zone. This helps distribute the load out over a period of time,
72rather than having all mirrors synchronize at the same time.

81Your mirror may not be added immediately to our listing and given access to the private distribution point. We add mirrors
82on an as-needed basis so as not to clutter up the listing, and to provide an adequate amount of high speed mirrors. You are more than
83welcome to peek in #gentoo-mirrors on irc.freenode.org and chat up to see the status of your mirror being added to our official network.

37<p>for new source mirror requests, the procedure will be as follows:</p> 95For new source mirror requests, the procedure will be as follows:
38<p>Someone asks to be a mirror, then we verify that the mirror exists and we can connect to it properly. Then we will contact you and enable your server to connect to <path>rsync1.us.gentoo.org</path>, the master rsync mirror. Then, in the next 48-72 hours we will determine if your mirror is syncing correctly with <path>rsync1.us.gentoo.org</path> and accordingly with this policy.</p> 96</p>
39 97
40<p>If all steps went smoothly, we will then add you to our list of <uri link="http://www.gentoo.org/main/en/mirrors.xml">download mirrors</uri> on the main web site.</p> 98<p>
99Set up your server to rsync with ftp.ussg.iu.edu::gentoo-distfiles. Once you
100have a complete mirror of that server, please file a bug report on
101bugs.gentoo.org under the "rsync" category stating that you have a new mirror
102and wish it to be added to the list of official mirrors. Please specify
103whether you wish to be a "Full" mirror or "Distfiles only" mirror. Distfiles
104only mirrors will be designated as such on the website.
105</p>
41 106
42<p>Additionally, you, the mirror admin will be added to the gentoo-mirrors mailing list (low traffic) so that you can folllow all issues associated with source mirrors. 107<p>
108Full mirrors must carry the following directories (plus any directories that
109get added in the future):
110</p>
111
112<ul>
113 <li>/releases</li>
114 <li>/experimental</li>
115 <li>/distfiles</li>
116 <li>/snapshots</li>
117 <li>/grp</li>
118</ul>
119
120<p>
121Distfiles only mirrors need to carry the following directories:
122</p>
123
124<ul>
125 <li>/distfiles</li>
126 <li>/snapshots</li>
127</ul>
128
129<p>
130We will then verify that the mirror exists and we can connect to it properly.
131Then, in the next 48-72 hours, we will determine if your mirror is syncing
132correctly and in accordance with this policy.
133</p>
134
135<p>
136If all steps went smoothly, we will then add you to our list of <uri
137link="/main/en/mirrors.xml">download mirrors</uri> on the main web site. We
138will also send you the login information for our private master distfile mirror
139which is only available to official Gentoo Linux source mirrors.
43</p> 140</p>
141
142<p>
143Additionally, you, the mirror admin, will be requested to subscribe to the
144gentoo-mirrors mailing list (low traffic) so that you can follow all issues
145associated with source mirrors.

185<title>Q: I run a private source mirror for my company. Can I still access the private master source mirror?</title>
186<body>
187
188<p>
189A: Because our resources are limited, we need to ensure we allocate them in
190such a way to provide the maximum amount of benefit to our users. As such, we
191limit connections to our master rsync and distfile mirrors to public mirrors
192only. Users are welcome to use our regular mirror system to establish a
193private source mirror.

213<title>Q: I don't have that much disk space. Can I mirror part of the sources?</title>
214<body>
215
70</p> 216<p>
217A: Yes, if you are unable to mirror our full sources, you can elect to mirror
218the following two directories only:
219</p>
220
221<ul>
222 <li>/distfiles</li>
223 <li>/snapshots</li>
224</ul>
225
226<p>
227These two directories will require approximately 40GB of space and you will be
228listed on our site as a distfiles-only mirror.

234<title>Q: Do I have to turn on Directory Indexing for directories served up via HTTP?</title>
235<body>
236
237<p>
238A: Directory Indexing is required for the /releases and /experimental
239directories, but can be turned off for all other directories (including
240/distfiles) if you wish.

246<title>Q: Do I have to mirror historical? I mean, it is old releases.</title>
247<body>
248
249<p>
250A: Of course not, it is quite a bit of data. In your rsync command, add
251<path>--exclude=/releases/historical</path> to your rsync options. This will
252exclude historical and save you quite a bit of space.
