The district court granted hiQ’s motion. It ordered LinkedIn to withdraw its cease-and-desist letter, to remove any existing technical barriers to hiQ’s access to public profiles, and to refrain from putting in place any legal or technical measures with the effect of blocking hiQ’s access to public profiles. LinkedIn timely appealed.
In short, the district court did not abuse its discretion in concluding on the preliminary injunction record that hiQ currently has no viable way to remain in business other than using LinkedIn public profile data for its Keeper and Skill Mapper services, and that HiQ therefore has demonstrated a likelihood of irreparable harm absent a preliminary injunction.
We conclude that the district court’s determination that the balance of hardships tips sharply in hiQ’s favor is not “illogical, implausible, or without support in the record.” Kelly, 878 F.3d at 713.

Most routers now do a per-flow load balancing, meaning packets on a TCP connection are always sent over the same path, but even a small percentage of routers with per-packet load balancing can cause the website to be unreachable for users behind that router.
所以 LinkedIn 的人試著測試 TCP Anycast 技術的穩定性:
So, to validate the assumption that TCP over anycast in the modern internet is no longer a problem, we ran a few synthetic tests.
測試的方式是設定 web server,讓下載速度不快,然後設了好幾個點並且放出對應的 routing,用 Catchpoint 服務監控,如果不穩定的話,應該就會收到 RST 中斷連線:
We configured our U.S. PoPs to announce an anycast IP address and then configured multiple agents in Catchpoint, a synthetic monitoring service, to download an object from that IP address. Our web servers were configured to deliberately send the response back slowly, taking over a minute for the complete data transfer. If the internet was unstable for TCP over anycast, we would observe continuous or intermittent failures when downloading the object. We would also observe TCP RSTs at the PoPs.
而好消息是,測試起來相當穩定:
But even after running these tests for a week, we did not notice any substantial instability problems! This gave us confidence to proceed further.
