Is it just me, or the site is super laggy now?

Not for me. Im from Argentina and its working just fine.

same thing from canada, works fine.

Ok, fine.

I was having a very bad connection to the site on that day, maybe 20 or 30 seconds for each page to load, if it did at all.
I'm glad it's not a website problem, since there isn't much anyone could do about it.

I think we should build some kind of archive of the best challenges here, in case the site does go down for some reason some day.

That sounds good, yet you wont know the password of some of the challenges that you didnt solve.
But its still a good idea to save the challenges, they really worth the effort.

After all these years, I still come here from time to time and try to solve some of them.
