 <h2>Downloading genome data</h2>
 <p>
 Most of the underlying tables containing the genomic sequence and annotation data displayed in the 
 Genome Browser can be downloaded. All of the tables are freely usable for any purpose except as 
 indicated in the README.txt file in the download directories. This data was contributed by many 
 researchers, as listed on the Genome Browser <a href="../credits.html" target="_blank">Credits</a> 
 page. Please acknowledge the contributor(s) of the data you use.  
 
 <h3>Downloading the data</h3>
 <p>
-Genome data can be downloaded in different ways:</p>
+Genome data can be downloaded in different ways using our North American and European download
+servers, hgdownload and hgdownload-euro.</p>
 <dl>
   <dt>Via rsync:</dt>
   <dd>
-  The UCSC Genome Browser hgdownload server contains download 
-  directories for all genome versions currently accessible in the Genome Browser. The rsync command 
-  <code>rsync -a -P rsync://hgdownload.soe.ucsc.edu/path/file ./</code> can quickly and efficiently 
-  download large files to your current directory (./). To download an entire directory (note the 
-  trailing slash), you would use an expression such as 
-  <code>rsync -a -P rsync://hgdownload.soe.ucsc.edu/directory/ ./</code> For more information please

 <h3>Types of data available</h3>
 <p>
 There may be several download directories associated with each version of a genome assembly: the 
 full data set <em>(bigZips)</em>, the full data set by chromosome <em>(chromosome)</em>, the 
 annotation database tables <em>(database)</em>, and one or more sets of comparative cross-species 
 alignments.</p> 
 <p>
 <em>BigZips</em> contains the entire draft of the genome in chromosome and/or contig form. Depending
 on the genome, this directory may contain some or all of the following files:</p>
 <ul> 
   <li>
   <strong>chromAgp.zip:</strong> Description of how the assembly was generated, unpacking to one 
   file per chromosome.</li>
