so every hour SondeHub is seeing a blip of requests spike. Nothing we can't handle. They look like normal browsers - though a splattering of user agents listed. I say normal because they load the requests very close to a normal page load would. All from the same network block. They then query for radiosonde serial numbers we have never seen. What is going on here. Whatever this person / agent is trying to do could be done in such a simpler way that costs us less money.
