[AusNOG] Google Public DNS via MegaIX Melbourne

[James Morgan]

We are certainly seeing strangeness into Google via the Megaport Melbourne IX at the moment.  Timeouts querying 8.8.8.8, users of Recaptcha reporting that their verification calls were failing so people were getting locked out of websites, etc.  Strangely another of our upstreams who is also connected to MegaIX Melbourne had this problem yesterday, but don’t seem to have it today.  Anyone else still seeing problems, or have any tickets open with Google that I can reference in ours?

James.

We saw all of our google traffic start routing through Sydney around 1240 yesterday. It normalized around 0500 today.
I don't bilaterally peer with Google over the MegaIX Mel fabric, just the route servers. I checked the MEL MegaIX looking glass and google's sessions were both down.
Cheers, Tim

Yes. We are. Since about 10.00 AM ACDT yesterday. Still ongoing today.

For Us:

-BGP session to Google A (103.26.71.181) refuses to connect.
-BGP session to Google B (103.26.71.182) connects, but we lose connectivity to 8.8.8.8 when it’s up.
-As soon as we shut down that second session, everything returns to normal.
-Our peering with Google in Sydney (IX AU) and MegaIX (Sydney) don’t seem to have any issues.

I’ve been working with Google NOC by email since yesterday and we’re not making much progress.

I’ll update them now that we’re not the only ones affected!

There is reports of a significant google outage which appears to have been resolved.

Hey Guys,

Anyone else having issues connecting to Google Public DNS via MegaIX in Melbourne? Confirmed reachable via MegaIX Sydney, as well as other peering providers in Melbourne, so may just be limited to MegaIX in Melbourne?

Regards,
Sean
