Facebook broke this morning!

Facebook is unable to access at all this morning, the broadcasting tells the phenomena is not restricted but all through the world. The Website reveals how vulnerable it is! I knew in the middle of the night, server error or something so I thought at that time. Datum in the Website might disappear if someone try to do that! It is true that the elimination of records written on the paper looks so convenient for saving space and the data might call back immediately, but on the other hand, the probability of missing datum cannot be denied. I know that the habitual behavior of backup datum is common sense, but inevitable disaster happens unexpectedly, so unfortunately at all. As the conclusion this morning, things invisible cannot be relied on completely however convenient it may be, the same is said also on SARS CoV-2.
