Can confirm the impact appears total for the Azure portal; Microsoft sells DDoS protection as part of Front Door and other Azure services. Do they not use it themselves?

> Microsoft sells DDoS protection as part of Front Door

They got in via a Back Door.

A lot of places sell DDoS protection. Most of it only ever cover the basics. With the size of botnets, hacked computers, etc that are easily and cheaply available for rent - a lot of so called DDoS protection services can't compete.

You really need to dig deep into what they mean by DDoS protection.

What layers are covered? What type of services are covered?

Also e.g. when they mention they cover volumetric attacks, it's often marketing more than the real deal.

E.g. a provider sells $x of total protection (that number means across all PoPs, so usually $x / 30 or less). It can still go down if you focus all your attacks on a few PoPs that matter.

You can tell the error on the Portal is coming from AFD thanks to the style/format of it.

Am wondering the same thing. I have yet to meet anybody that does aside from Microsoft themselves.

Flawless instant access for me. Clearly not a total impact. Didn't even notice until I saw the headline.

You are too late to the party. The problem was between 15:10 UTC and 17:30 UTC on 9 Jun 2023.

It's very odd because it's only new page loads. Existing metrics pages I've been refreshing keep showing new data.

We see the same thing. One of my team is sailing around in the portal, even opening new tabs and it all is just working.

But I can't create a new session, even when remoted into an Azure-hosted VM. All our servers and services seem to be running fine; it just seems to be the portal.azure.com website that is impacted.

Probably because the actual portal service call happens at new page load. Metric pages and everything else are data plane/control plane info most likely, which is coming from other services.

An easy way to validate this would be using fidler or similar to analyze the traffic that happens in the loaded page.

That would be hitting separate API endpoints which are not hosted in the same place as the portal itself.

I don't really understand how a DDoS can happen when the portal is using MS routing. Should be a simple fix. More likely some misconfiguration.

i wonder how much traffic it would take to DDoS Azure's Web UI. You're talking about like 1,000,000+ orchestrated/coordinated silently hijacked machines all... what? curl'ing in a loop some API of theirs?

I'm working on it right now, 45 minutes after the submission. Maybe not everywhere? Maybe fixed already?
