We detected no managed anti-bot vendor on upenn.edu’s homepage. That does not mean the whole site is open: deep pages frequently flip to bot-managed, so check the exact URL you intend to scrape.
A plain HTTP client reaches it — no managed anti-bot detected.

Homepage-level, datacenter-IP snapshot, June 13, 2026.
This is a homepage-level snapshot and can be inaccurate or out of date — anti-bot vendors update their models continuously, deep pages are usually more protected than the homepage, and difficulty is IP-sensitive: a site can read differently from a clean vs a flagged IP and even flip over time. Treat it as a directional signal, not a guarantee.
The homepage is the open front door. On a education site the valuable pages behave differently — here's the plan to characterise upenn.edu before you build.
