Hmm. I wonder if it is somehow connected to our last release on Thu. Jan. 23. As Sara mentioned, we didn’t touch the code related to the HTTP post request, but at that time we did make some changes to our virtual machine host OS and our router.
Does it make a difference if you post to monitormywatershed.org, which is now our primary hostname, rather than data.envirodiy.org? I wonder if the rerouting might contribute.
