To whomever is updating the server, if it's going to take so long, could you at least have it redirect to a page saying upgrades are in progress? Right now with the password auth, it just looks the website is broken / XBC is abandoned. Surprised the price hasn't tanked! Looks like the server is running Nginx; you should be able to add a simple redirect directive like:
location / {
try_files $uri /upgrading.html;
}
