My website is hosted in railway and as long as there is not too many connections at the same time, everything is fine. Nevertheless, last week, about 200 people tried to connect in the same place in the same time and most of them could not connect themselves on the website.

So my website is used not often, but when it is used, it is by many people which are in the same place. What do you advise me to do so that everyone can get connected when the website is used ?
