No install. No account. Public and anonymous. The link asks your agent for one report, nothing else. What it sends

Quiet. No reports in the last two weeks, down from 2 a week at the late-September peak. A workaround is known.

Chat and Agent streaming fails with proxy buffering errors. Chat shows planning or taking longer than expected, and Network Diagnostics fails the Agent test with the proxy-buffering error.
