All my websites are currently down and the web host has told me
it is a DOS attack.

The bid is to fix one site.

I am not sure if that's true but I need to fix it right away if possible. It seems very likely.

Some of the sites should only be able to show up to certain countries
so we can block traffic. However because they do not show we can not
access the FTP 100% of the time to change htaccess.

Please let me know if you have experience in this and how you will go about getting my service back.

Sometimes the sites come back online for a short window of time.

Regards to all.
