"I assume those companies connect with Bandwidth privately versus public Internet." I've asked on here if anyone is connected to Bandwidth.com via PNI and still having issues, but I haven't seen anything back. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com ----- Original Message ----- From: "Jared Geiger" <jared at compuwizz.net> To: "VoiceOps" <voiceops at voiceops.org> Sent: Wednesday, September 29, 2021 11:20:31 PM Subject: Re: [VoiceOps] Bandwidth - Monday Outage Bandwidth.com is behind Cloudflare now instead of NTT presumably for DDoS protection. Then Cloudflare Magic Transit wasn't so magic today. https://www.cloudflarestatus.com/incidents/kctplzfbf2j2 VoIP needs to decouple from the TDM PSTN legacy so we can get federated and authenticated ENUM IP peering at IXPs or something similar to what the GRX/IPX does in the mobile world. I'm sure this exists to some extent between the big guys already, but us little guys need in on the action to make services more robust. I'm surprised more people haven't complained that Google Voice and Microsoft Teams numbers aren't working. I've been too busy to test during these outages to test. I assume those companies connect with Bandwidth privately versus public Internet.

I've worked with every major ILEC and RBOC and the amount of anti-competitive tactics I've witnessed over the years has always been through the roof because there was never a motivation for the big guys to share their networks with the little guys. These kind of tactics are nothing new, so I suspect the attack originated from a domestic player/group of players and Bandwidth will not be their only target. My suggestion to everyone would be to make your networks as redundant as possible so you don't have to rely on any one carrier. Don't burn bridges with any carriers either because you never know when you might need them again.

This smells very fishy to me. The fact that a long-term attack has been targeted at one of a few companies that host other carrier's services AND provides 911 services the weekend before STIR/SHAKEN's implementation takes place does not appear to be a coincidence to me. Carriers fight attacks off every day, but In all my years of working in the industry, I've never seen an attack last so long that it had the potential to take a carrier out of business. In my opinion, this wreaks of anti-competitive tactics. Whoever is doing this to Bandwidth seems to have a lot of resources and purposely intends to take Bandwidth out. Call me crazy if you want, but when I smell fish I'm usually not wrong!

While we all might love to know what they?ve done to TRY to mitigate the issue; it?s reasonable to assume that they?d be fairly quiet about what they?re doing/trying to do. Right now, I?d rather them keep a low profile and simply get the issue addressed. You know they?re hemorrhaging customers left-and-right due to port-aways.

Is this some sort of ransom event against them maybe? And what are the rest of you telling your customers? We seem to have only a few specifically complaining, but those are complaining a lot.

I too have heard unofficially that its DDOS, which makes sense given the recurring nature.
4.5hrs down Sat
Our monitoring showed 2 hours 47 minutes of actual service affecting outages across Voice (Inbound and Outbound), Messaging, and API/Portal.
The issue started at 3pm and recovered at 5:47pm EDT. We reported it to the TAC at 3:07pm, they did not post on Status until 3:31pm.
Some small downtime Sun
Now deep into Monday with problems.
Its not a good look, but id like some more transparency.
DDoS attacks are real and hard to null route. You've got millions of IP addresses slamming you with data. Your router has a capacity, and your router cannot handle all of that extra crap data along with all of our traffic too.
I'm sure BW will be investing in some beefy hardware that will be able to better handle DDoS attacks, as well as working more closely with their peering providers. I have to assume that they were getting gigabits of traffic, overwhelming their links in addition to their edge routers.
Cloudflare details how they do it here:
https://support.cloudflare.com/hc/en-us/articles/200172676-Understanding-Clo...
Not much to be transparent about. The Internet is an unfriendly place, and bad actors can rain hell upon any public IP they want. Unsecured laptops, desktops, TVs, IOT devices, etc, all contribute just a little tiny bit, and all focus on one single point, kinda like those giant solar farms with the mirrors and single tower in the middle to boil the molten salt.
Well, Bandwidth is the molten salt, and the mirrors are a bunch of unsecured devices on the Internet.
