Can't Blog in My Wordpress during the Day and at Night

I dunno whether it is the Streamyx problem or my blogs server.

It will take ages for me to login to my Wordpress blogs during the day and night time. Even at 2am in the morning, I still can't login.

The only time when the login is fast is around 8am to 9.30am. By the time I come home from sending my girls to kindy, it is already 8.30am. So I only have one hour to blog if my son did not wake up early. If he does, then no blogging in my Wordpress blogs for that day.

I have no problem loading other websites. I even get a friend from Singapore to login into my Wordpress blog; no problem too, very fast.
