Hi. Today I’ve had a problem that made me wonder if 1.1.1.1 is reliable enough, because this problem happens over the years like 2 or 3 time per year.
This two queries have been made one after the other, when I got an error that github com cannot be resolved. Was there any problems with 1.1.1.1 today like until about two hours ago?
