MW2 Beta Connection Failed – What Is Detrick Guernsey Error?

If you’re wondering why your connection failed to the MW2 Open Beta servers, we’re going to explain what the Detrick Guernsey error is.

The excitement for Call of Duty’s upcoming installment, Modern Warfare 2, is keeping players hoping for the best COD yet. And thanks to the beta, we’ll finally be able to experience it.

Betas are limited-time opportunities for fans to get their hands on their most anticipated games, and the Modern Warfare 2 open beta is no different.

However, you may log in to see if you can play before being met with a connection failed error, with the code being “Detrick Guernsey”. Fortunately, we have the answer for you.
