State Department upgrades its unclassified computer network

After many incidents and leaked information, the State Department announced, on Friday, its decision to upgrade the unclassified computer network, trying to prevent any future cyber attack, in the mean time having his employees unable to use their email or connect to the internet.
According to Department spokeswoman Jen Psaki’s words: "the security of its main unclassified network during a short, planned outage of some Internet-linked systems.", having in the background the cyber attack, which took place in November. Therefore, the danger which faces the network is real and incidents, like the one mentioned, give the State Department enough reasons to gather up their resources and build a better defensive system against potential hackers or foreign agents. It’s not the first time when the employees stay resource less at their work place, since the same situation happened few months ago.
Declaring that the department continued to monitor any unusual activity on its unclassified network, Psaki refused to approve the existence of any recent cyber attack
The question, whether has been one cyber attack or more in the last weeks, has been left with no answer, being up to you to figure it out
