[IPv6crawler-wg] Routing problems resolved on IPv6 Day

Hello All,
one good thing about IPv6 day is that if there was any kind of routing
problem, because everybody was watching, those were resolved fast.
For example, have a look at this thread, which I have pasted back
together - taking the www.ipv6matrix.org upstream routing transient
problem issue which appeared from time to time.
Throughout the day, the IPv6-ops list was kept very busy. I never told
anyone on the list about the occasional problem, but since we had a lot
of exposure yesterday, someone picked this up quite spontaneously.
Please see the chronology of things below (whilst of course keeping in
mind that the chaps at 2020Media, our hosting provider, were also
enquiring directly with their upstream about what was going on)
If there was one take-away for this IPv6 day, it's that a lot of small
problems like this were fixed in a matter of hours, and that was really
great!
:-)
Kind regards,
Olivier

ping-pong is still on...
Judging from your output, hop 13 must be LINX (hop 6 in my output).
Then going through 2a01:178:9191:3::17 in your output vs
2a01:178:9191:3::200 in my output.
Trying a trace on LINX LG (226.x peers), it returns your path.
Trying a trace on LINX LG (224.x peers), it returns my path (or "Command
timed out").

>From the same computer but two different IPv6, I get different result
(as16347 for both). One is working and the other is looping between
"2a01:178:9191:3::200" and "2a01:178:9191:3::1"
Maybe there is loadbalancing based and source IPv6 and one the router
doesn't know the right route ?
The first one :

Etc...
The other one (same computer, same /64 but different IPv6) :
