Yes. The system is completely automated and reliable. There is nothing to be concerned about. Quite simply, nothing can go wrong, go wrong, go wrong... go.. Seriously though-- In order to be black-listed by our system you would have to be abusing the SNF software or using some alternative software to attempt to gain access or deny access to the SYNC servers. Otherwise the most you could do would be to loose contact for some time. That said, if any system does something to become black-listed then you can be sure it will have our attention. It is basically impossible for you to cause a properly functioning SNF node to become black-listed by altering the configuration file. It is far more likely that your SNF node would simply fail to connect. Chances are that if you were making an adjustment that could cause this you would also be watching to make sure that things were working correctly when you finished. In case you did cause the system to lose it's connection with us, the system is designed so that SNF nodes will remain reliable and effective for extended periods even if they are unable to contact the SYNC server. It is also designed to recover gracefully when the problem is corrected. The GBUdb system is highly effective even when it does not share it's information with the other SNF nodes. Each GBUdb node learns first about it's local traffic. As long as your SNF rulebase file is up to date - or even close to being up to date, your system is likely to be very effective at filtering spam. If your SNF/GBUdb node becomes detached from the main system for an extended period, it will degrade in it's performance. Once the problem is corrected it should recover in a very short time. In the event we detect any IPs being black listed or acting suspiciously we will be watching closely so that we can analyze any potential threats and take appropriate actions. If we can identify a customer involved in such a case we will contact them to investigate and correct the problem. Locally, your status reports indicate when the last sync event occurred. This is one of the ways you can check the status of your system. Consider this example from recent telemetry: <timers> <run started="20070928174736" elapsed="1620714"/> <sync latest="20071017115919" elapsed="11"/> <save latest="20071017111334" elapsed="2756"/> <condense latest="20071017081746" elapsed="13304"/> </timers> You can see when the last sync event occurred (about 11 seconds ago in this case): <sync latest="20071017115919" elapsed="11"/> We plan to encourage the development of third party tools for monitoring and analyzing SNF system data. In addition we plan to build monitoring and analysis services of our own to include features that will notify system administrators when something doesn't look quite right. If you (anyone) develop something nice for displaying and/or monitoring SNF status data then please share it with the SNF community. In the mean time - we have done extensive testing and monitoring throughout the development process. High availability is (has always been) a design requirement and we're confident SNF can deliver that.
