Absence of an internet connection could lead to inaccessibility of data.
Internet speed and bandwidth could restrict the reliability of accessing data.
In addition, the accessibility of data also considers the reliability of cloud servers themselves.
Downtown of cloud servers could lead to data being inaccessible.
Cloud service provider's employees could access data stored on cloud servers.
Hackers could breach cloud servers and access data.
Cloud Server Uptimes
