Routing Issues Portugal send to Israel

cdn

#1

Users in Portugal :portugal: are connect to Israel :israel: that’s ~2500km
There plenty of closer Cloudflare colos closer.
It is way off the normal operation.
Anyone seeing this behaviour?

colo=TLV
http=h2
loc=PT
tls=TLSv1.3
sni=plaintext

#2

Was this a one-off thing or can you consistently reproduce that? If this was not a temporary glitch I’d definitely open a support ticket and have them check that routing.

Can you share the domain in question?


#3

Seeing this across many domains, started at ~01:00 UTC today:


#4

IPv6 maybe? Can you switch to v4 on that connection?

Though that is a slightly weird IPv6 address, but I guess that will be an output glitch of Cloudflare -> @cloonan


#5

Seems to be 2001:8a0::7b5, part of AS 3243.


#6

This routing issue continues:
Basically, IPv6 2001:8a0:: in PT are all routed to TLV

@cloonan do you have feedback on this?


#7

After digging Cloudflare workers logs, users in GB, HU, PT were affected, and all IPv6.
This information is now with Cloudflare Network team


#8

Perfect, thank you. I see the ticket, made some notes from this thread and cc’d myself on it.
