       <h3 id="aka">AKA domain</h3>
  -    <p>An ‘AKA domain’ creates a parallel version of a site (or domain) for our redirection software so we can check redirects are correct before we put a site live.</p>
  +    <p>An AKA domain creates a parallel version of a site (or domain) for our redirection software. This allows us to preview redirects before going live.</p>
   
       <h3 id="archive">Archive</h3>
       <p>In the Transition app, ‘archive’ is a link to a page on GOV.UK with the option of either viewing the old page on the National Archive website or going to the new organisation’s GOV.UK homepage.

  -    <h3 id="canonical">Canonical</h3>
  -    <p>The ‘canonical’ list has all duplicates removed and creates a single version of mappings to work on.</p>
   
       <h3 id="dns">DNS</h3>
       <p>The Domain Name System (DNS) connects domain names (eg www.gov.uk) with a server address. The switchover itself happens when the DNS entries for your site are changed to point at our servers, enabling our servers to redirect or show Archive pages.</p>
  
positive.code:     <h3 id="subdomain">Subdomain</h3>
      <p>Subdomains are domain names which have a parent domain name. For example: en.wikipedia.org and www.wikipedia.org are different subdomains of their parent domain wikipedia.org.</p>
  
      <h3 id="tna">TNA</h3>
      <p>The National Archives is the government organisation responsible for creating archives of UK government websites to maintain the public record in the digital age. The Transition app provides users with a link to TNA to view archived pages on transitioned sites. Here is a link to the Web Archive homepage: http://webarchive.nationalarchives.gov.uk/</p>
  
      <h3 id="tna-timestamp">TNA Timestamp</h3>
      <p>The National Archives Web Archive will produce snapshots (or “crawl”) of a given website, which are labelled with timestamps, for example 20100202072553 is for a snapshot taken on the 2 February 2010 at 07:25:53.</p>
  
      <h3 id="ttl">TTL</h3>
      <p>Time To Live. This is the number of seconds for which a DNS record can be cached by your computer, for example, before being checked with a DNS server. We ask for the TTL for your sites to be lowered to 5 minutes before switchover so that there is a clean cut-over - rather than different users getting the old or new site until the change has propagated. Commonly TTLs can be set to a day, which would lead to poor user experience as they would see the old or new site unpredictably.</p>
  
      <h3 id="url">URL</h3>
      <p>A URL is how a web browser requests pages, images and other data from a website.</p>
