As a European citizen, I hadn't been aware of the weather in the US, so my first thoughts were:
1/ Maybe my cable modem is acting up again;
2/ Maybe my ISP has DNS troubles;
3/ Maybe RJN is ill;
4/ Maybe this particular server is down;
5/ Maybe an underground internet cable has been cut.
Only after reading
geckzilla’s post did I realize what had happened.
Then I wondered, how many times have there been no APOD? It can't be many. I think the service has been remarkable steady and reliable over the years.
