Not able to make use of promotions!

I love the airline! Yet, when advertising their one day, 45 000 low-fare flights for today, and even promoting the fact that they have measures in place to ensure that their website do not crash - the opposite happens, The website immediately goes to an "504 Gateway Timeout", since 8 am this morning/ This makes it impossible to benefit from the opportunity, thus one does not even take these promotions serious?
