Identification of the site

The URL-encoded address

• http%3A%2F%2Fp2pool.co%3A9332%2Fstatic%2Findex.html

decodes to:

• http://p2pool.co:9332/static/index.html

This location matches the standard built-in web interface of a P2Pool node (a decentralized mining-pool protocol/software). In the classic Bitcoin-era P2Pool software, port 9332 is commonly used for miner connections and the node’s local/public HTTP status UI. (p2pool.in)

What “Try the Fastest Mining Pool” refers to

“Try the Fastest Mining Pool” is best understood as a promotional line shown on (or alongside) a mining-pool web UI, not as a person or organization name.

In other words, it is not a uniquely identifying “who”; it is a slogan associated with the web page you referenced.

“Who” runs p2pool.co:9332?

What can be stated with high confidence

• p2pool.co:9332/static/index.html appears to be the statistics/status page of a P2Pool node (i.e., a node operator is hosting a P2Pool instance and exposing its web UI). (p2pool.in)
• P2Pool is decentralized: many independent operators run nodes, and there is typically no central operator for “P2Pool” as a whole (and node operators can be pseudonymous). (reddit.com)

What cannot be reliably determined from the provided URL alone

• The real-world identity (person/company) behind the specific node p2pool.co:9332 cannot be determined from the URL by itself, and may not be publicly disclosed (even via WHOIS, depending on privacy/proxy registration).

How to find the operator (practical verification steps)

If you need attribution, typical approaches are:

1. Check the page itself (/static/index.html) for an “About”, “Contact”, “Fee”, or “Operator donation address” field (many public nodes include one).
2. Look up domain registration (WHOIS) for p2pool.co (not the port number), noting that privacy/proxy services may obscure the registrant.
3. Search for announcements (forum posts, GitHub, Reddit, Bitcointalk) where an operator advertises their node by domain name.

If you want, tell me which coin/software you believe this node is for (Bitcoin P2Pool vs Monero P2Pool are different projects), and I can outline the most likely identification paths accordingly.
