Hello.

There is a Denial of Service attack in progress against GMAT Club that started about 8 hours ago. This attack is particularly focused on search-related functionality. We have been banning IP Addresses and doing other things; however, we are only being reactive in that case. As the result, we had to disable search-related functionality to keep the site from getting overwhelmed and up and running.

We will re-enable search-related features either when the attack stops or once we have been able to write code preventing flooding of the search system, which will happen sometime on Monday. So.... worst case scenario, it will have to wait till Monday.

Sorry about this and appreciate your understanding.

Hi bb

What was it all about?



Unfortunately I do not know why or for what reason anyone wants to try out a DoS attack on GMAT Club but I guess people who are bored find our forum and try things out.... it is disruptive and sometimes takes the site down though not for long, usually. This time they focused their efforts on the Search-related areas, so we had to disable them for about 12 hours to get through the wave. We are good now and a bit more prepared for the next wave when it comes (they come every 2 months or so).

Thanks for asking.
BB
