eqseis.geosc.psu.edu is a subdomain of Penn State University, a trusted academic institution. It has been around for over 20 years and has never been flagged on any blacklist. However, when we tried to access it, the site presented an invalid SSL certificate that doesn't match its domain name — a clear sign that the server configuration is broken. As a result, the site is currently unreachable.
For educational resources, it's normal to have minimal contact pages or legal footers, but a working SSL certificate is essential for any site that wants to be taken seriously. Without it, your browser will block the connection, and there's no telling whether the content you'd see is genuine or has been tampered with.
If you're a researcher looking for seismic data from Penn State, this domain has historically hosted such information. But until the certificate is fixed, you won't be able to access it securely. Keep an eye on it, but don't rely on it in its current state. If you find a working version elsewhere, be cautious — the original site's problems suggest it may be abandoned.
