Widget no longer working

Hi all,
For some reason as of Tuesday this week I noticed that the weather widget was no longer working. I tried to access the weatherfor.us site to contact the developers, but the website appears to be offline and I am getting a 502 error, Bad Gateway.
Is there anything I can do to get this widget up and running again?
Regards,
David
