> So at the end, our explanation is way more *probable* (we definitly do not need to cheat to solve those challs and even if we would never have cheated in a such visible way), but it is also *verifiable* (just check about the downtime!)

Verification above, you are lying.

@solarwind I'm not sure about this lack of server downtime. We constantly had problems with the scoreboard page loading, basically all the time you had to refresh it a couple of times in order to get in, so I can imagine someone giving up and stashing the flags for later, especially since they still had plenty of time to submit.

Also I know for a fact that at least two tasks had flag submission broken, according to orgs `Its laggs of cloudflare`, and it could be that all flags were affected by this issue (we had only two to submit at the time so I don't know). For sure we couldn't validate web 100 and some other task at `Aug 25, 2017, 9:32 PM CEST` and we managed to submit only about half an hour later. Maybe downtime was localized somehow due to cloudfare and only some teams experienced this?

Anyway, both @khack40 and @sec0d are teams with a long history of playing in CTFs and I can't imagine them cheating on some random noname CTF out of the blue. I also don't see why should it be necessary. There were ~4 of us playing (and by no means all the strongest ones), and yet we were still able to get pretty high.

There were also no really really hard tasks which could distinguish between a medium and a strong team (there were no statistics on number of solves for tasks so I can't be sure on this). There were some hard-guessy stuff like web200, or hard-broken ones like crypto300 but it was more about luck and not only skill so it's not a benchmark in this case. Unlike in some hardcore CTFs there was no crypto solvable only by Hellman and a couple of others, or pwn which only j00ru and a few other people could tackle etc. Basically any task could have been solved by a lot of teams, so I can totally imagine a "medium team" winning or at least getting to the top with enough manpower, dedication and a bit of luck.

There is no need of imagination, if there are facts. And facts here -- there are strong signs of cheating in submission timing, and team is caught on lying publicly about submission server downtime. In that period they are talking about other teams successfully verified flags, see above.
Explanation that Cloudflare failed for only 1 team for ~12 hours is not much better than they guessed 4 flags in 5 minutes.

@solarwind
Facts : Our members got trouble to submit flag.
Cheating issue closed.

Please stop lying, submission server was working fine in that period.
You were asking previously to check your claim that server was down -- you got verification.

Please stop whining.
You got fucked hard by @sec0d and @khack40 didn't share any flag.
Now, you have to accept that.

@solarwind you don't work in statistics, do you ?
You managed to find "significant" "proof" of cheating using 2 data points lul
(also why would khack40 cheat on a small CTF like this one ?)

Now please be sportsmanlike, it makes the game way less fun when you get cheating allegations coming from nowhere, from a team who's not even part of the organization but still managed to get the logs somehow...

Analysis above showed that you & sec0d cheated, it is funny to see how you are switching to insults from lengthy posts with fake excuses when got caught on lying.

@solarwind, you already got too much attention for your cheating allegation.
Your analysis above just prove that during 2017-08-26 20:55:43 to 2017-08-27 09:44:34 some teams validated flag.
It don't prove that platform got 100% uptime.
You got response from orgs.
You got response from sec0d.
And you got response from us.
I repeat one more time, during that 12 hours (we were sleeping first of all), then we found 4 flags and we got submission trouble.
Is it our internet connection ? Is it platform downtime ? Is it like the scoreboard page loading issue ? I don't know and I don't care.
Deal with that because you won't get another response.
