Hi Jenia. Thank you for fixing the mapping for my site.
Regarding your question, as soon as I confirmed my registration for simplywell.me any WordPress.COM page was unavailable. A blank page would appear, and sometimes the "Problem loading" message would show up. I used multiple browsers (Firefox, Safari, Explorer) multiple ISPs, and computers; and would get the same result. So I could not access the forums or other blog sites, the admin page or even my own blog and dashboard.
WordPress.ORG was fine and when I attempted to get support from that site I was turned away. It seems like there were several users who were affected by this issue. Total time, WP was inaccessible for about 12 hours.
Hope this information is helpful.
