Upload redacted W3C .log or FREB .xml files. Queries, IP addresses, and usernames are omitted from the output.

Ready when you are.
ABOUT THIS TOOL

Use the report to guide a targeted investigation.

W3C files require a #Fields header including cs-uri-stem and sc-status. Time buckets use logged UTC dates and times. FREB evidence is summarized separately because it can describe requests already in W3C logs. Limit: 20 files, 20 MB each, 50 MB total, and 200,000 W3C rows. Source line numbers are retained, but raw logs and query strings are not packaged. Paths and filenames can still contain identifiers; redact before sharing.
