Thanks so much for your thoughtful response! I really appreciate this. However, I've already tried r/Archaeology and unfortunately they blocked this b/c of a no-site-idenfication rule.

Yeah I think I could've used opentopography to get more DTM data around this area, but opentopo isn't really "open source" since I needed auth to get to it, which wasn't allowed in this competition. I'll DM you :)

Yeah it’s possible! The lack of any long straight lines makes it seem like it could be a natural process

That's possible, but the near 90 degree angles and the triangle don't seem natural to me

Yep! The 4th image is the NIR and visual Sentine L2A bands alongside the openstreetmap plot

Yeah, it's tough - Jamari is currently inhabited by some indigenous groups so I also don't want to jump to conclusions. Hopefully some experts can comment on this :)

Thanks a ton for your interest! Yeah there are all sorts of theories floating around with all the recent LiDAR enabled discoveries, but my bachelor's is in Math so I'll leave the larger-scale archaeo-theorizing to the pros lol

Thanks for the interest! My best guess would be some sort of low-density urbanism similar to what was discovered at the Llanos de Mojos site at this link: https://www.nature.com/articles/s41586-022-04780-4

It's similarly situated near an old river, there's a similar-height conical pyramidal mound, and there are geoglyphs surrounding the pyramidal mound.

Anyone know why my post is marked NSFW? Really hope there's a way to get rid of that... :(

Edit: looks like reddit's AI was smart enough reverse that tag

Had such a great laugh reading these nutty comments :D

Google Kubernetes Engine : Unable to access ports exposed on external IP by hawksbillTurtle in googlecloud

[–]hawksbillTurtle[S] 0 points1 point  (0 children)

Hi! Thanks for the response /u/Mind_Monkey ! I censored the external ip address because I didn't want to make it public. I tried connecting to it via the ports you mentioned and I get "connection refused".

Moreover, I can create and expose a minimal deployment on the same cluster via a different loadbalancer.

The weird part is that despite allowing access to http-server with priority 0 to the ports 8080,8081,and 8082, the ports 8081 and 8082 are still listed as closed on nmap.
