    The Gory Details
    First, the outage of January 20th was not caused by a software or hardware failure, but was instead
    due to an administrative error at the Corporation for National Research Initiatives (CNRI).
    The domain name “doi.org” is managed by CNRI on behalf of the International DOI Foundation (IDF).
    The domain name was not on “auto-renew” and CNRI staff simply forgot to manually renew the
    domain. Once the domain name was renewed, it took about 48 hours for the fix to propagate
    through the DNS system and for the DOI resolution service to return to normal.
