While CCP attempts to have the System available at most times, CCP does not guarantee that the System will always be available, or that the System will not become unavailable during Game play. The System may become unavailable for a number of reasons, including without limitation during the performance of maintenance to the System, for the implementation of new software, for emergency situations and due to equipment or telecommunications failures.
i feel like people don’t read the EULA.
Also, it may not be on CCP’s end… it may be somewhere between your router and CCP.
