I appreciate the update, but your service has been unavailable for hours already. This is unacceptable for a service whose core value is to ensure that we know about any incidents.
Flush your DNS like the parent said.

#462To get on github you can add to your /etc/hosts: 192.30.253.113 github.com 151.101.32.133 assets-cdn.github.com And it seems faster than normal right (less users).

Given that a large swath of SaaS services, infrastructure providers, and major sites across the internet are impacted, this seems harsh. Are you unhappy with PagerDuty's choice of DNS provider, or something else they have control over? I don't think anyone saw this particular problem coming.
Re: DDoS Attack Against Dyn Managed DNS
#465I wanted to provide an update on the PagerDuty service. At this time we have been able to restore the service by migrating to our secondary DNS provider. If you are still experiencing issues reaching any pagerduty.com addresses, please flush your DNS cache. This should restore your access to the service. We are actively monitoring our service and are working to resolve any outstanding issues. We sincerely apologize f…
How am i meant to see twitter status updates when twitter is down?

#466Re: DDoS Attack Against Dyn Managed DNS
#467Surprised to see so many big names relying on a single provider. DNS is designed to be distributed, it should be possible to avoid a single point of failure.

You apparently don't understand DNS. DynDNS is a very reputable DNS provider that twitter and many others use. For someone to take them down requires a massive amount of effort. Running a redundant DNS provider is expensive as all hell.
Route53 on AWS is $0.50/zone and $0.40/million queries. API integration is also very easy.
Using something like Route53 as a backup is significantly cheaper than suffering from the current Dyn outage.

It's called a false flag operation, and does happen.
And the ratio of false flag operations to false accusations of false flag operations is about 1:99. Lots of unlikely things "do happen," but if that's the immediate explanation you reach for you're going to be wrong most of the time.
Where did I say it was my immediate explanation and this is _likely_ what is happening?
