A barracuda web filter crashed over the weekend during it's automatic update and prevented access to the Internet for everyone.
For the users, I have a active directory group policy enabling proxy settings for it's address 'BARRACUDA' and port '3128' (user configuration > windows settings > internet explorer maintenance > connection > proxysettings) Simply reversing the policy was sufficient to allow access for users again.
To prevent such issues in the future: What, if any, intermediate device can I point to that will allow browsers to bypass the barracuda filter if it goes down again?
Or, is their some setting on the barracuda device that will route traffic through regardless if it's hung up? (I ask this since I have no access to configure the device myself)
