Hello AkuKreok,
The servers are not down. I suppose it has something to do with your Internet connection or with your browser.
You may try the following:
Clear your browser cache. If you're not sure how to do this, you can Google it. Instructions are available for every browser.
Try logging in with a different browser, such as Google Chrome, Firefox, etc.
Re-start your router or cable modem.
If none of this works, please read the FAQs

before you contact the technical support

Kind regards,
John
