Sorry to jump in late, but I'm trying to understand why the community string doesn't get stripped when traffic comes back clean? Isn't that the whole point of a scrubbing center, to remove the bad stuff and then... remove the label too?
Or is the community not about the traffic itself but about the route announcement?
So: dirty traffic arrives at your edge, your edge sees 64512:9999 and sends it to Singapore. Singapore scrubs it, sends it back clean. But if the return route still has 64512:9999, your edge says "oh this still needs scrubbing" and sends it to Singapore again. Loop.
The scrubbing center is supposed to strip that community before announcing the clean prefix back. Or their route reflector is supposed to not re-attach it. Someone forgot.
6 hours now. Still no response to my ticket. Kenji3 you got escalated because you quoted ana_mad's number. I quoted it too and got told "that ticket is not available to reference." They are lying or their system is broken or both.
I am moving 2 VPS to OVHcloud Singapore this weekend. Done with Contabo routing — https://contabo.com/en/vps/.

I'm in Toronto so I use Beauharnois. No scrubbing there though, just raw bandwidth.
This is why I don't let providers touch my routing. I announce my own prefixes from Manchester, if I need scrubbing I use a third party that just gives me a clean feed and I control the communities myself. More work, fewer surprises.
Contabo is cheap for a reason. You are the product and the QA department.
Probably unrelated but the timing is suspicious. Could their route reflector hiccup have propagated beyond just scrubbing customers?

I don't have visibility into their full customer cone though. Anyone else see prefix weirdness from Contabo Singapore yesterday ~14:00 JST?
I did a quick check from Frankfurt. traceroute to a Contabo-hosted site I know was going via Singapore for about 10 minutes around 06:00 UTC, which is 15:00 JST. Normally that path goes London-Nuremberg. So something was definitely shifting routes in their Asia network yesterday.
I don't have an account with them so I can't see more. Just a data point.
Following this thread closely. I was about to order Contabo scrubbing for a project in Mumbai. Now I'm hesitating.
Does anyone know if their Mumbai scrubbing center has the same setup? Same route reflector or separate?

If you do go ahead, test with a /24 you don't care about first. And set up your own monitoring with something like Pingdom or UptimeRobot, don't trust their status page. I learned that the hard way.
