<div id="mirrorstatus" class="box">
    <h2>Mirror Status</h2>
    <p>This page reports the status of all known, public, and active Arch Linux
    mirrors. All data on this page reflects the status of the mirrors within
    the <em>last 24 hours</em>. All listed times are UTC. The check script runs
    on a regular basis and polls for the <tt>lastsync</tt> file in the root of
    our repository layout. This file is regularly updated on the central
    repository, so checking the value within allows one to see if the mirror
    has synced recently. This page contains several pieces of information about
    each mirror.</p>
    <ul>
        <li><em>Mirror URL:</em> Mirrors are checked on a per-URL basis. If
        both FTP and HTTP access are provided, both will be listed here.</li>
        <li><em>Last Sync:</em> The timestamp retrieved from the
        <tt>lastsync</tt> file on the mirror. If this file could not be
        retrieved or contained data we didn't recognize, this column will show
        'unknown'.</li>
        <li><em>μ Delay:</em> The calculated average mirroring delay; e.g. the
        mean value of <code>last check − last sync</code> for each check of
        this mirror URL.</li>
        <li><em>μ Duration:</em> The average (mean) time it took to connect and
        retrieve the <tt>lastsync</tt> file from the given URL. Note that this
        connection time is from the location of the Arch server; your geography
        may product different results.</li>
        <li><em>σ Duration:</em> The standard deviation of the connect and
        retrieval time. A high standard deviation can indicate an unstable or
        overloaded mirror.</li>
        <li><em>Mirror Score:</em> A very rough calculation for ranking
        mirrors. It is currently calculated as <code>hours delay + average
            duration + standard deviation</code>. Lower is better.</li>
    </ul>
    <p>The final table on this page is an error log, which shows any errors
    that occurred while contacting mirrors. This only shows errors that
    occurred within the last 24 hours.</p>
    <ul>
        <li><a href="#outofsync">Out of Sync Mirrors</a></li>
        <li><a href="#successful">Successfully Syncing Mirrors</a></li>
        <li><a href="#errorlog">Mirror Syncing Error Log</a></li>
    </ul>

    <p>The last mirror check ran at {{ last_check|date:'Y-m-d H:i' }} UTC.</p>
