Hmmm, looks like you might be on to something. From HE6in4:

root at alpha:~# for i in `dig mx gmail.com +short | cut -d' ' -f2` ; do 
printf "%-25s%-25s" "`date '+%x %X'`" "`dig AAAA $i +short`" ; e=`curl 
-6 -sSm 5 $i:25 2>&1 >/dev/null`; r=$?; echo "$e $r" ; done
05/07/2014 11:19:09 AM   2607:f8b0:4002:c01::1b   curl: (28) connect() 
timed out! 28
05/07/2014 11:19:15 AM   2607:f8b0:400e:c03::1a   curl: (28) connect() 
timed out! 28
05/07/2014 11:19:20 AM   2607:f8b0:4001:c03::1a   curl: (28) connect() 
timed out! 28
05/07/2014 11:19:25 AM   2607:f8b0:400d:c04::1a   curl: (28) connect() 
timed out! 28
05/07/2014 11:19:30 AM   2607:f8b0:400c:c01::1a   curl: (28) connect() 
timed out! 28

 From native IPv6:

root at test:~# for i in `dig mx gmail.com +short | cut -d' ' -f2` ; do 
printf "%-25s%-25s" "`date '+%x %X'`" "`dig AAAA $i +short`" ; e=`curl 
-6 -sSm 5 $i:25 2>&1 >/dev/null`; r=$?; echo "$e $r" ; done
05/07/2014 11:14:29 AM   2607:f8b0:4001:c03::1a    0
05/07/2014 11:14:29 AM   2607:f8b0:400d:c04::1a    0
05/07/2014 11:14:29 AM   2607:f8b0:400c:c01::1a    0
05/07/2014 11:14:30 AM   2a00:1450:400c:c05::1b    0
05/07/2014 11:14:30 AM   2a00:1450:4013:c00::1a    0

No issues with IPv6 web traffic though. Anyone else seeing this?

Regards,

SG
