[smokeping-users] Curl Graphs blank?

[Pete Hoffswell]

Good day!
 
I have been encountering blank sections within trending charts on some CURL probes.  I would have expected them to go red, if there was no response.
 
What does this mean? I cannot find in the documentation or searching the list.
 
I've posted a representative graph here:

Anyone know why this happens?
