Its a shame you are under DDOS attack but a 'protection' system that takes us out as well isn't so great.
There is so little profit to be had these days that dropping out unpredictably for hours isn't much use.
eg; dropping out for 2 hours in 24 means a 8% loss

Can you let us know when you think its sorted, and I will switch back?

Thanks

I have used trademybit.com in the past but they have a tendency to mine some risky coins unless you mine to a specific port and choose the coins yourself.
For instance, they currently show 0.00102 BTC/day/mhash using X13 against APEX
That's where I am off to until nicehash sort themselves out.

That's better:

Maybe I will change my script to pick the best coins over on trademybit instead?

Can not connect to X11 or X13 (again!!!!)

I used to like nicehash but these dead periods are getting silly.
Is it just me or it is time to look for a more reliable service?

I have a nvidia rig which works with a homemade script to switch between X11 and X13 (nvidia loves those two!) but that isn't causing me to get blocked or banned is it?
I check the profit every 5 mins and switch accordingly.

Thanks
