Monitoring
Starting at 11:30 UTC, we started to experience connectivity and latency with a few of our services including image resizing and social media posting to Twitter. We've seen during this time significant posting delays, so you may see your posts going out 3-4 mins behind schedule.
This looks to be the result of an upstream DDOS attack on a DNS Provider (Dyn). They are mitigating the attack and we're starting to see some resolution. We'll be posting regular updates on the recovery here.
