We inform you that tonight at 2 p.m. the I'm sure.gr will be offline, due to scheduled work maintenance and service improvement.
If all goes well, (see Murphy's law), the work will be finished in 20 minutes, and 2:20 we will be again online.
This work is the first in a series tweaks which will take place in the next period on the server. The goal is the (even) better performance of the site.
Thank you for your understanding.
