How often do you notice in technological errors?

[Matan_z]

Technology makes our life easier and simpler yet like any other thing it has errors and bugs and that can be truly a mess.
Even the smallest thing as of a searching Error on Google or a buggy Ad such things are counted as errors.
We all want everything to work smooth without any distractions to either slow us or make things hard and so it's not fun noticing in such errors in our daily basis.
So my question is how often do you notice these errors?
