Dear Dear colin johnston,
Your probe 2317 has been disconnected since 2015-06-21 18:49:16 UTC.
This is an automatically generated email from RIPE Atlas. It was sent to you because you asked to be notified if your probe becomes disconnected for more than 30 minutes.
If you want to change this, or disable this notification altogether, please go to 
https://atlas.ripe.net/probes/2317/, and click the "edit" button under "Notifications".  
Kind regards,
