opkg update failing today - 503 Service Unavailable

I'm getting this at the terminal when I run "opkg update":

root@myyun:/mnt/sda1# opkg update

This with a google.com ping so I know access to the internet is good:

And the link to to the openwrt file on this page is broken too:

Is http://downloads.arduino.cc/ down entirely or am I missing something?

Thanks

@i8flan, downloads.arduino.cc and www.arduino.cc are NOT the same machine. They are not even located in the same building. The server named download.arduino.cc goes down from time to time, sometimes for days.

The message you got that included 503 Service Unavailable, can be interpreted as such:

The server is currently unable to handle the request due to a temporary overloading or maintenance of the server. The implication is that this is a temporary condition which will be alleviated after some delay.

Please wait and try again. Let us know in 24 hours, if you can access those files.
Also, FWIW, I cannot access the files either. I am in El Paso, Texas, USA.
Wait. I got the main file, but the checksum failed. Try in a few hours also.
