The WSPRNet.org web pages are back this morning and these numbers are quite astounding :
"Spot Count
1,294,073,014 total spots
1,118,021 in the last 24 hours
10,816 in the last hour
"
Over a million spots a day added to a database of over 1.2 billion. Just the bandwidth required to handle the traffic to add a million spots a day must be growing like crazy then you get the likes of WSPRView users querying it every two minutes and getting their downloads of 400-500KB each time. Server drive space could be running low too given the data accumulation rate.
I'm probably not helping either. My WSPR beacon project has been getting significant numbers of spots from all over the globe on 10 and 14 MHz with fewer on 18, 21 and 50 MHz. Given that it transmits on a different band in every two minute period, that becomes a near-continuous feed of spots with some bands producing many spots and others few and sometimes none ( = no prop or no stations monitoring). At least in MyCall mode, WSPRView only queries the spots database every 10 minutes so that is a reasonable amount of data in the overall total.
Not much we can do about it other than be patient and use it when available.
PS.
(1) The greatest distances noted for my transmissions are from EA8-land, Canary Islands, so that must be close to my antipodes position - while I always thought it was closer to the UK.
(2) The optimal frequencies to work DX on HF would have to be 10 and 14MHz at the moment and I am guessing FT8 on those would be the best target mode (I think only VK has SSB on 10MHz). Some of the signal reports on 10MHz have been astounding based on a 5W transmitter power into an untuned antenna wire & ideal for digital comms (eg FT8). Mornings, afternoons and night - there seems to be propagation to somewhere.
