Fix Markdown for Agents savings calculation

• Fixed a bug where the Markdown for Agents savings metric included conversions not served to AI bots or crawlers, overstating the median response size since August 27, 2026. Historical values are corrected on Radar and in the API.

Add AS-level connectivity and upstream providers widgets to Cloudflare Radar

• Added an AS-level connectivity graph to AS routing pages, aggregating the BGP paths an AS uses to reach the Tier-1 networks across every prefix it announces, as observed by selected RouteViews collectors. A Show full paths toggle switches between the simplified view and all observed paths, and an IP version selector switches between IPv4 and IPv6.
• Added an Upstream providers timeseries widget to AS routing pages, tracking the share of an AS's observed paths carried by each direct upstream network over time. Up to 10 upstreams appear as their own series, with the remainder grouped into Other.
• Added two new endpoints to the BGP API:
• /bgp/routes/paths/{asn} - Returns the ordered AS path segments an AS uses to reach the Tier-1 networks, each with its observed path count, peer count, and contributing collectors.
• /bgp/routes/upstreams/{asn}/timeseries - Returns the share of an AS's observed paths carried by each direct upstream over time, split by IP version.

Add TLS bug detection to the Radar post-quantum TLS support checker

• The post-quantum TLS support checker now reports TLS bugs detected during the handshake test (Split ClientHello, HRR Failure, Unknown Keyshare) with user-facing descriptions and remediation guidance. The bugs section only appears for hosts where issues are detected.
• Bug detection data is returned by the existing /post_quantum/tls/support endpoint.

Add new routing widgets to Cloudflare Radar

• Added a Top ASes by announced IP space chart to country routing pages, breaking down the IPv4 and IPv6 address space announced from a country across the top originating autonomous systems.
• Added an RPKI ROA deployment timeseries widget to the RPKI sub-page, tracking the share of announced BGP space covered by a valid Route Origin Authorization (ROA) over time, with a toggle between covered prefixes and covered IP address space. Available on global, country, and AS views.
• Added two new endpoints to the BGP API:
• /bgp/ips/top/ases - Returns the top autonomous systems by announced IPv4 or IPv6 address space, globally or filtered by country.
• /bgp/rpki/roas/timeseries - Returns RPKI ROA validation coverage over time, by share of prefixes or share of IP address space, split by IP version, with optional ASN or location filters.

Add signature agent URL to bot details

• Added signatureAgentUrl field to the bot details API endpoint. For agents verified via Web Bot Auth, this field contains the URL to the agent's HTTP Message Signatures key directory. It is null for bots not verified via request signature.
• Added signature agent URL to the bot detail page on Radar, with a modal to inspect the key directory JSON content.

2026-04-01

Promote Routing to a dedicated section with sub-pages

• Expanded the Routing page into a full section with dedicated Overview, RPKI, and Anomalies sub-pages.
• Added new Top 100 ASes widget to the routing overview, with rankings by customer cone, IPv4 address space, and IPv6 address space.
• Added new RPKI prefix validation widget showing per-ASN prefixes grouped by validation status (Valid, Invalid, Unknown).
• Improved the IP address space chart to display both IPv4 and IPv6 trends on all views including global.

2026-03-06

Add region filtering and AS/location dimensions to API
