Threads Critical latency degradation in checkout-edge worker Share

What I did

I queued an autofix that restores the Hyperdrive pool hd-prod in the coreplane/checkout-edge repo with:

  • max_connections restored from 5 to 50 on the pool binding
  • a regression test that fails when checkout queues on the pool
  • wrangler.jsonc configured to deploy as checkout-edge

This gives Boris a PR with deployable code. Once merged, running wrangler deploy will replace the degraded worker with the fixed version.

The root cause report has been updated with the occurrence #2 evidence: Root Cause: checkout-edge Latency Degradation (Recurring).

调试是迭代的。 Polylane和你一起迭代。

  • 自动开始

    已确认的故障会自动开启一次调查。你也可以随时对任何东西点击“调查”。

  • 每个假设都有律师

    智能体分别担任控方、辩方和中立方，各自深挖不同的证据：日志、指标、追踪、变更、代码。

  • 没有证据就等于没发生

    没有数据就判为无法确定。仅凭相关性永远不会被称为原因。

  • 一个答案，有据可查

    智能体投票，一份总结落到问题上，通常在半小时以内。明确的根因会启动修复。

每一条结论都引用来源。 带编号的引用，直至原始工具输出。

智能体运行你真实的工具：可观测性提供商、云、GitHub、一个代码沙箱、上下文图。对你的云的写入会暂停并展示确切的调用；在你批准之前什么都不会执行。

看的是论证过程，而不只是答案。 每一次工具调用、每一个判定，都在一份可分享的记录里。
