A firewall is similar to a security system which protects your computer from the outside world and others on your network. It filters incoming Internet traffic while allowing you (and those behind your firewall) to communicate with the Internet. The firewall can help protect your computer from unauthorized users accessing your system by only allowing requests you made to enter your computer.
A firewall is very important in securing your computer. It can help to prevent certain types of viruses from infecting your computer as well as prevent hackers from gaining access to your system.

ITF and LC Datacenter firewall upgrades. No downtime is expected as firewalls are in redundant pair.
Scheduled work: An end of row switch has experienced failed ports. The switch will be rebooted and if necessary replaced with a spare. The switch in question is located at the south end of row BA. Impacted cabinets and device owners will be communicated with in a separate, more focused communication.
