Uh, my sanity is restored :)

As for your comment about the network, yes my dev setup is in EU (yet its 250Mbit up/down fiber, typically no issues here with Internet otherwise, but of course anything can happen :) and again switching back and forth between 10.19 and 10.30 all the time, where 10.19 does't have issues) However, I can reproduce it from my test site in US just as well. Test site is in AWS with pretty biffy setup on the East Coast? (us-east-1, i..e supposed to be closest to IB servers, ?t3.2xlarge instance aws claims 5gbit network, ok it is probably less in reality but itis not likelly a bottleneck even it is "just" 500Mbit to the Internet ).?
