 The switchover agent is able to create and close incidents on uptime status pages.  (Production is located at [https://status.loginproxy.gov.bc.ca/](https://status.loginproxy.gov.bc.ca/)).  To do this, two environment vars must be configured:
 
-- UPTIME_STATUS_PAGE_ID: This integer can be found in the status page's non-vanity url for the statu page hosted by uptime.com.
+- UPTIME_STATUS_PAGE_ID: This integer can be found in the status page's non-vanity url for the status page hosted by uptime.com.
 - UPTIME_STATUS_TOKEN: The credential used for the uptime.com API.  It can be found [here](https://uptime.com/api/tokens).
