Our upstream provider opened up a ticket with Level3 late this afternoon. Hopefully it will be resolved, soon.

Our upstream provider has three dual-stacked transit providers and they shut down the Level3 IPv6 peering, but then we lost access to another third or so of the sites. For example, ipv6.t-mobile.com is only visible to us from Level3, same with www.globalcrossing.com. ipv6.cablelabs.com is with HE and Level3 and we should be able to get HE via Sprint, but we lost visibility anyways.

Thanks, Teun.

Someone else pointed to me offlist that this could be just our prefix, 2607:fe28::/32. I've already contacted our upstream provider who buys the transit from Level3.

I monitor over 30 IPv6 hosts, and starting around 1:54 am (Central) I couldn't access about a third of them. Here's the list of sites that I currently can't access:

Just ran a few tests from 88 host in 78 ASN's, 24 countries:

...
