Well, I have to say thank you very, very much. Thanks to your advice we have our lowest latency in 3 years! Sub 300ms average. As expected though, we are now sitting on 21 billed f4 instances, which will potentially cost us in the order of 3x our current ($30-40 -> $100+), but we will tweak that from tomorrow onwards. Peak hour is about to hit so we are going to see if the system can keep sub-300ms at the current "automatic" setting for scaling. But yes, once again, thank you for solving in 5 minutes what I have been working on doing for 2 weeks (my tears are from joy and sadness all at once)
