It's a typographical error. Person B almost certainly meant to say:
It's working fine from here.
In this context, "from here" means "as seen from my computer". In other words, person B means that he just checked the Internet Archive, and it worked fine on person B's computer. So, either the problems that person A experienced were temporary and have stopped now, or those problems are due to something other than the Internet Archive being closed. Perhaps a router or other computer on the Internet, which normally would transmit information from the Internet Archive to Person A, is not working.
As Stephie pointed out, m and n are near each other on a typical keyboard (and f and t are near each other, too), so a typographical error seems likely. Autocorrect may have "corrected" fime to time instead of fine.
