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.
ietf.org has physically diverse secondaries so it strikes me as unlikely that this problem is outside sprint ietf.org. 86400 IN NS ns0.amsl.com. ietf.org. 86400 IN NS ns1.ams1.afilias-nst.info. ietf.org. 86400 IN NS ns1.mia1.afilias-nst.info. ietf.org. 86400 IN NS ns1.sea1.afilias-nst.info. ietf.org. 86400 IN NS ns1.hkg1.afilias-nst.info. ietf.org. 86400 IN NS ns1.yyz1.afilias-nst.info.
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.
