[Outages-discussion] IPv6 outages overnight

I monitor over 30 IPv6 websites and Wednesday night between 11:52 pm and
Thursday morning 12:50 am Central four of those sites became inaccessible
almost all at the same time.
ipv6.t-mobile.com
www.t-home.hu [just the one AAAA: 2001:4c48:2:46::1b:1]
www.twtelecom.com
www.t-online.de
Those sites (currently) go over different transit links (two over Sprint,
two over Level3).
Here are traceroutes from 2607:fe28:10::/48. Unfortunately I was not awake
when this happened, so I couldn't see where it failed. BGPlay on the IPv6
and IPv4 prefixes I tried don't show any routing events at our upstream
transit during those times.
Anyone else see anything around that time?
