American Red Cross:

I know you have other things on your plate right now, but you seem to have a DNS problem.

The name server arcdns3.redcross.org (162.6.90.141) either doesn’t exist, or is broken. Unfortunately, the Top-Level DNS servers still have it on file.

The site is working great [here]. Except for the DNS issues.
Keep up the good work.
