I have found and fixed a problem with the scraping of the wsprnet.org spot data.
It appears that recently the wsprnet.org servers have become more heavily loaded and as a result they are frequently taking longer than 10 seconds to respond to my scrape requests.
By increasing my timeout from 10 to 120 seconds, I am getting data from almost all of my requests.
Please let me know if you find spots in wsprnet.org that are not reported by wsprd.vk7jj.com
