[Outages-discussion] Upstream DNS failure? Multiple sites and services not loading.

[Greg Dickinson]

I actually get an SSL error on 9to5mac.com, it says it's serving the cert for gcg-re.com.  If I proceed I get a 500 error.  Non-TLS connections give a 403.

I found that http://secure-web.cisco.com/1gewFyef3CQk7RHqP3tUP6SjdEHrgtbYjgarhE4-FItXvK3-jt4FEFAnV1U98Q9KJFSpQxdyQM3_S8CVjdk0JJ3bzohJ3wnGGRA0MKLPgFp0Ep66bTqxNH-7XU29LRRhd5EJJPOVI71UjNC7kSOt4ot3FE4_J4_p3NXaqbzgt51x2rDqeLw0ocvjMxyh1uw1N_sxFPS9K25lSk1EajfynXF3wNgYHIVgz6i4tTguhw9leM1HAhR8VGpJmyk5LD5ueWTUm8nkK60Z9JF47yinSoWyXSt1GdhNa-SpFygtoZYLgzdncDVBj3nGPKPPijFz4/http%3A%2F%2Fwww.9to5mac.com did not load this morning.  Others online say they can reach it. 

Then I looked at http://secure-web.cisco.com/1JCBshhoHLuz7gXGxRlyeNgmVJVTbeHOfK-L7ubjPn1BF6leTHoKP8_P4Cy5Yt7rwRfhjPR8_LE-3eCtB_MB58qMnlY4Vz9I3Hvai8oDSdaZZZOSsAcmdm9yAOxACd9Ht48vHHBez9bM8aQhlnRtdi7Lo0Hx0EDBQPESvSbtcDJNrpMeusYVE4jWa0VvvsCYS7RjXlIsCUiqXyWzJYbF-XYL3TywBPMfRqf1jrzI1HazS2KzSb-kS35v6vlY9G0Y3e0mZ4xvXfd1CjyuAd1xPb076x4QLHfaUHZzqCxs9RygFAlDYA4ShN4h40RFn8GY2/http%3A%2F%2Fwww.downdetector.com and saw spikes in reports for EA, AT&T, T-Mobile, Pokémon Go, and Metro (cellular).  

This widespread disruption points to a major backbone or DNS disruption somewhere.  Anyone else seeing odd behaviors this morning?
