Sprint Wireless DNS server not resolving ietf.org

[Yang Yu <yang.yu.list () gmail com>]

ietf.org and its subdomains such as tools.ietf.org are not accessible
on Sprint 3G/LTE (DNS timeout). From what I gathered this is affecting
Sprint wireless customers nationwide. I created a DNS measurement on
ripe atlas and no signs of other carriers experiencing the same issue.

Emailed Sprint NOC and opened a ticket via support channel, got no
update. Is there someone from Sprint Wireless on this list?

DNS servers
68.28.169.132
68.28.168.132

Thanks.
