Yes - your ISP just has shitty IPv6 routing (ie. poor peering and transit agreements).
Happens on one of my lines as well (“experimental” IPv6 support that basically reaches only 1/3 of the internet).
Even Europe's largest hosting provider (OVH) has some IPv6 issues (their routers seem to ignore your existence if you do not keep spamming NDP NA packets).
