DNS Outage?


There seems to be a pretty widespread DNS-related issue at the moment. Does anyone have insight as to the root cause?

So far it seems to be an Akamai internal DNS look up problem. That is, it seems if they need to resolve the hostname of the origin to serve a page they front for, it fails but I haven't seen any actual DNS failures on my side or other places, just inside Akamai-served pages saying they failed to resolve with an Akamai reference code.

I can't speculate on cause, but it certainly is incredibly widespread. Just about every service shows a spike in problem reports: https://downdetector.com/

Seeing a "Service Unavailable - DNS failure

The server is temporarily unable to service your request. Please try again later."

on many sites.

Related thread (that I just opened)[0]. It's affecting the major brokerages.

Will be interesting to see the postmortem on this.

According to pingdom about 30k sites affected at the peak.

👤 dialtone
anyone using akamai as a CDN is having issues, if they use it also as a DNS they won't even resolve their primary domains.

Probably related - carriers are reporting AS701 BGP issues with Verizon at Equinix NY2 datacenter.

DNS is decentralized, but it seems like Akamai breaking breaks a huge swathe of websites.

Possibly Akamai?
