this is probably a stupid question but what am I am supposed to do when something like this happens while installing ?
It depends what command you ran.
If you used pacman -S package to install a package, you can use pacman -Syu package instead.
If you were doing a system update when you received that message, then comment out the first mirror from your list.

You might need to update your mirrorlist.
Assuming you have rate-mirrors installed,
rate-mirrors arch | sudo tee /etc/pacman.d/mirrorlist
In case you’re in India, this could help 
i still keep getting this mirror problems
I have already tried to use this rate-mirror and updated mirrorlist. I also trried to update my mirrors via the Welcome screen. But nothing help.
Even when i do pacman -Syu i get this problem.
