Weblock is currently in beta. You can already use the service, but things may still change a bit.

How to Read Weblock Link Reports

Summary: On top of the report you will find the summary of total number of citations, citations with web links and the percentage of obsolete links (links that are broken for different reasons).

Visualization: Right below you will find the visualization of failed links versus links that resolved fine, a top-level summary of http response classes, and more detailed summary of http response codes for failed links.

Log File: Further down on the report you will find the log file with details for each URL that was found in the references list and tested by the WEBLOCK service. In particular, you will find the current http status code that was returned when trying to access the link. The http status codes 2xx indicate valid links. Status codes 3xx, 4xx and 5xx indicate obsolete links - links that either vanished or need additional, case-specific actions to perform properly. All links with status codes 3xx, 4xx or 5xx are thus considered obsolete links. The status code 444 is not an official status code and is used by our service to indicate links that timed out, i.e. links where the server took too long to respond or where no server responded at all - the latter typically happens when a website is completely gone and the host can not be resolved to an IP address via the DNS system.
