It seems that there has been a massive short lived ddos attack all over the web.

There have been several in the later years. Sone of them are linked to a botnet called AISURU that it's supposedly infected millions of devices worldwide.

Timing links most likely with an attempt at hybrid warfare against europe. My bet is israel or Russian linked due recent events.

No, that's what the common prejudices about the popular whipping boy of the moment says.
