You should get use to it. LBC is constantly on and off quite frequently, and when it is working, sometimes there are other problems (like delays in notification, online status, hold on deposits/withdraws, etc)
You're right - Pro Trader (lol) for 1 1/2 years now - just seems like it's been sluggish for past 2 weeks with new server upgrades/cloudflare - down time longer than usual.
That being said,
I'm currently logged on - loading times are still slow for now,
Those 2 escrows I previously mentioned have auto-canceled - cool
EDIT: 23:53 GMT Site's still struggling atm - was able to change my Margin, but it's currently Timing Out
