  + <h3>Noticeboard for 2019</h3>
  <p>Any updates or disruptions will be listed below.</p>
  <ul>
  - <li><strong>14-18 June</strong> Following the switch to the new ONSPD CSV schema, <code>longitude</code> and <code>latitude</code> for entities with no geolocation were returned as <code>0</code> and <code>99.9999...</code> instead of <code>null</code> and <code>null</code>. Old behaviour has been restored as at 19th June (version 9.0.1)</li>
  - <li><strong>29 August</strong> A data centre network failure caused 6 minutes of outage (between 17:25 UTC and 17:31 UTC). After the API was restored, there was elevated response latency for ~30 minutes as more resources were brought online to compensate for lost capacity</li>
  - <li><strong>30 August</strong> Between Aug 29 17:31 UTC and Aug 30 14:39 UTC, the API returned incorrect longitude values on the <code>terminated_postcodes/</code> endpoint. Longitude was incorrectly reported as <code>null</code> for a subset (321,831 of 851,354) of terminated postcodes</li>
  + <li>No issues to date</li>
  </ul>
