Was the Dynamo outage separate? My take was the NLB issue was the root cause and Dynamo was a symptom which they flipped some internal switches to mitigate the impact to that dependency
- easton 1y agoIf their internal NLB monitoring can delete the A record for dynamodb that seems like a weird dependency (like, i can imagine the nlb going missing entirely can cause it to clean up via some weird orchestration, but this didn't sound like that).
- nijave 1y agoI was thinking more along the lines of the NLB being in front of DNS servers and dropping resolvers Or an NLB could also be load balancing by managing DNS records--it's not really clear what a NLB means in this context Or there was an overload condition because of the NLB malfunctioning that caused UDP traffic to get dropped Obviously a lot of reading between the lines is required without a detailed RCA--hopefully they release more info
