I must agree! LoTW has been a Godsend from the day it started! I remember waiting months to years for a QSL... Yesterday I worked 4S7, and yesterday I got a confirm from that 4S7... If it takes a day, or two oh well... LoTW is so much faster than the old card method, (but I do miss the paper), it is silly to carp about it being slow for a few days, for Gods sake-- we are not launching a space shuttle, it's a QSL card, and in the past it used to take months to get, now it takes hours... I see no problem, other than I want it now, not in a few hours being the issue...
As a few of our foreign friends said, if they don't like it, they don't have to use it... It would be nice if they did, but it is their choice.
Our foreign friends are the reason many of us in the USA use LoTW. I have 290 countries confirmed via LoTW and I only had to bring 50 cards to my card checker so if LoTW was mainly being used for domestic verifications it would lose its appeal.
I don't think this current backlog was caused by the WAE contest. I'm pretty sure LoTW was slowing down days, or perhaps a week before the contest.
They simply need to fix the problem and pronto. LoTW is generating plenty of cash.
