In the mean time, if you do manage to get onto the above two sites, be warned that there are no areas where you will be asked to login. There's also no possibility to purchase anything, so if asked, do NOT give over any credit cards or any information about yourself.
UPDATE: Just got an email from the hosting company that there is a server issue. However, please play it safe and follow the above advice just in case it is more sinister than a server issue.
