Thanks for the link, I did actually check out the links on that page and they all seem to return the correct geoip.  I didn't see any specific contacts for Level3, unless I missed it?

Someone did reach out to me off-list, so fingers crossed they can get it resolved.

    Hey All,

    For my dayjob I help run an Anycast DNS network and we've recently
    had
    complaints from our users in the APAC region that sites using
    Level 3's
    CDN have poor performance.  Upon looking into this, it seems that
    they
    (Level 3) have incorrect geolocation data for some of our Singapore
    servers and are returning IPs for CDN servers in Australia. I've
    validated the WHOIS information for the blocks in question is
    correct,
    and every GeoIP site I check against comes back as Singapore, so this
    must be some internal database.

    I've tried emailing the whois contact, as well as the technical
    contact
    for the domain footprint.net <http://footprint.net> but have yet
    to receive a response.  Wonder
    if anyone else has been able to get in touch with the CDN people
    at Level 3?

    Cheers!
    Chris
