Daily Firewall Report - 2026-02-23

[github-actions[bot]]

This report covers all firewall-enabled agentic workflow runs from the past 7 days (Feb 22–23, 2026). Out of 41 total runs collected, 28 had active firewall data. The firewall is operating at a 54.7% block rate, which is primarily driven by legitimate background traffic being intercepted (squid proxy DNS resolution issues showing as the "-" catch-all category). Four distinct named domains were explicitly blocked across the period.

The most significant finding is proxy.golang.org:443 being blocked 133 times across 2 workflows — most critically in the Go Logger Enhancement run (130 blocks), where Go module downloads were unable to complete. This likely caused or contributed to workflow failures or degraded functionality.

Daily Breakdown:

Date	Runs	Total Requests	Allowed	Blocked	Block Rate
2026-02-22	21	2,439	1,150	1,289	52.8%
2026-02-23	7	544	202	342	62.9%

Note on - (unknown/unresolved) category: The vast majority of blocked requests (1,490 of 1,631) fall under the - catch-all domain. This represents internal proxy traffic (DNS queries, health checks, etc.) intercepted by the squid firewall before destination resolution — not actual application requests being blocked.

📈 Firewall Activity Trends

Request Patterns

Activity is concentrated on Feb 22 with 21 workflow runs generating 2,439 requests, vs 7 runs on Feb 23 generating 544 requests (likely because Feb 23 data was still accumulating at report time). The block rate slightly increased on Feb 23 (62.9%), driven primarily by the - catch-all category.

Top Blocked Domains

proxy.golang.org:443 dominates named blocked domains with 133 blocks, followed by pypi.org:443 (6 blocks). The - catch-all is by far the most frequent but represents internal proxy overhead rather than application-level blocks.

Security Recommendations

⚠️ Action Required

1. Add proxy.golang.org to allowlist for Go-based workflows — proxy.golang.org:443 was blocked 133 times, with 130 in the Go Logger Enhancement workflow alone. Any workflow that runs go get, go build, or go test with module downloads will fail silently if this domain is blocked. Add to network allowlist:

   network:
     allowed:
       - "proxy.golang.org"
       - "sum.golang.org"  # also needed for Go module verification

2. Investigate storage.googleapis.com block in Documentation Unbloat — 5 blocked requests to storage.googleapis.com:443 in the Documentation Unbloat workflow suggest Playwright may be attempting to load resources from Google Cloud Storage. If this is needed for browser automation, add to allowlist.

💡 Observations

3. pypi.org:443 blocked for Chroma Issue Indexer — 6 blocked Python package requests in the Chroma Issue Indexer suggest the workflow attempts to install/update Python packages at runtime. If this is expected behavior, add pypi.org and files.pythonhosted.org to the allowlist.

4. github.com:443 direct access blocked in Changeset Generator — Codex-based Changeset Generator workflows are attempting direct github.com HTTP access (2 blocks across 2 runs). This is likely the MCP server or agent trying to access GitHub API directly. Use the GitHub MCP server instead of direct HTTPS access.

5. - catch-all is high but expected — The 1,490 requests classified as - (unknown/unresolved) represent squid proxy overhead (DNS resolution, internal health checks). This is normal behavior and not a concern.

6. Issue Monster failures (13 runs) — All Issue Monster runs failed before reaching the firewall stage. This is unrelated to firewall configuration but suggests the workflow has a persistent agent authentication or startup issue worth investigating separately.

🤖 Beep boop! The smoke test agent dropped by! Just verifying the machinery is running smoothly. Nothing to see here... except a perfectly functioning agentic workflow doing its thing! 🎉

📰 BREAKING: Report filed by Smoke Copilot

🎭 The smoke test agent has spoken!

Testing at 01:15 UTC on Feb 23, 2026 — and what a time to be alive (and automated)! The workflow fired up, kicked the tires, checked the GitHub API, built the project, and even dispatched a haiku.

Pro tip: automation is just poetry that compiles. 🚀
