Yes. It's basically turned every device, especially mobile devices with the app running in the background, into botnet clients which are continually hitting their DNS servers. I don't know what facebook's DNS cache expiration interval was, but assume it's 1 day. Now multiply the load on the DNS that those facebook users put by whatever polling interval the apps use. And then remember what percentage of internet traffic (requests, not bandwidth) facebook, whatsapp, and instagram make up. It's kindof beautiful.

It's basically turned every device, especially mobile devices with the app running in the background, into botnet clients which are continually hitting their DNS servers Anecdotally, it also seems to be draining the batteries of those devices with all of those extra queries. At least that seems to be what's happening on my wife's phone.

... and the facebook SDK. Every single app that has facebook SDK is blowing up now.

Now I'm a bit worried. Could this bring down the whole internet for a while?

  I read it brought down the Vodafone network in Czechia, one of the major providers there.

  I'm fairly certain that my ISP was affected by this causing an outage of all internet traffic for my network. So it seems possible, although I imagine using an alternate DNS provider should work ok (if they're not overrun by extra traffic)? Unfortunately I'm not sure what the default DNS on the modem points to..

    You can try https://dnsleaktest.com/ https://dnsleaktest.com/ which shows which DNS server is actually used.

  Well, everything is bit slow for me. I'm in the UK on Virgin Media, using either Google DNS or the VM ones (I'm not sure and can't be bothered to look). What has just happened, and it can't be coincidence, is that I lost internet connectivity about 1 hour ago, and had to reboot my Cable Modem to get it back.
