How to Read HTTP 403 in WebsiteDown Results
In WebsiteDown, 403 often appears when target sites block datacenter probes, specific regions, or request signatures. That usually means “up but blocked”, not fully down.
If you see this code only in one region, compare with official provider status and retest from another network. Mixed regional results often indicate routing, policy, or edge differences rather than full global outages.
For deeper triage, compare this with the HTTP 429 guide, HTTP 503 guide, and the false-positive monitoring guide.
Most Common Root Causes
- WAF or bot-protection policy denies the request.
- Geo restrictions or ASN-based blocking rules.
- IP reputation blocking from threat-intelligence feeds.
- Permission rules deny anonymous or unauthorized access.
What to Do Next
- Compare results across regions to spot geo/policy differences.
- Check official status pages to confirm provider-wide impact.
- Test from a second network (mobile data, home ISP, VPN off/on).
- Review firewall/WAF logs if you control the target system.
What to Avoid During Triage
- Do not label 403 as global downtime without additional evidence.
- Do not keep retrying blocked requests aggressively; this can worsen reputation.
Real-World Examples
- Example: one region returns 403 while others return 200 due to geo policy.
- Example: WAF blocks automated probes but allows browser sessions with JS challenge.
