This is just tcp to 207.241.224.2 port 80 (delivered via curl) or from a router.

SYN goes out, nothing comes back.

I can't reach it from AS16509 (AWS eu-west-2), AS17547 (MOne in Singapore), AS18106 (Viewquest Singapore), AS20712 (UK), or AS4755 (Tata in India)

I can reach it from AS23674 (Nayatel Pakistan), AS174 (Cogent in US), AS3356 (Level3 in US), AS46887 (Crown Castle in US) and AS7545 (TPG Sydney)

I can also reach it via mozillavpn on AS39351 (London) and presumably other sites

Multiple machines, multiple ISPs, multiple ways to the internet. Very odd.

Thanks for confirming it's not fully broken though
