If you’re using the test revision of the WordPress Akismet plugin and seeing messages about connectivity problems, don’t be too alarmed.
Akismet is up. Our servers are working. Our network is fine. We are not experiencing any service difficulties.
We’re still sorting through the reports to find out why people are seeing error messages.
In most cases, the error messages are correctly reporting that a firewall is preventing connections from reaching Akismet.com. This problem is caused by the web host, not Akismet, and only the web host can fix it.
In some cases we’re seeing reports that may indicate spurious errors. This may be a bug in the diagnostic code, a conflict with another plugin, or an intermittent network issue at the web host – we’re still investigating.
Update: We’ve found a timing bug in the diagnostic code that can cause the Akismet plugin to report an error when in fact everything is working normally. The bug affects the diagnostic feature only; spam checking still works as normal. Version 2.2.5 of the plugin will be released shortly with a fix. In the meantime, clicking the “Check network status” button on the Akismet Configuration tab will normally remove the error message.
Update: Akismet 2.2.5 is released with a fix for the timing bug.
The issue is not a connectivity problem, but a spurious error message that is produced when connections are actually working fine.
