Why do brokers need to constantly reset their servers?

It seems odd that companies who live and die by providing online services would not have reliable servers. So why do brokers need to constantly reset their servers. I am on IBFX and they reset their demo server daily. Their live servers seem better, but still annoying.

They just so happened to reset the server right during the asian session when things started heating up in cable and eurusd. They had a ton of time after NY and before asia where there was little activity.

It also seems ridiculous that they can't warn us of these things. You'd think we'd be able to either:
A - Have a website we can check to see when they will reset the servers
B - Get a mailbox alert through MT4 saying they will reset our server in 5-10 minutes.

Why do they need to reset the servers so often?

Every broker I've been dealing with has some kind of Service Level Agreement in the contract you signed that allow them to stop the plafrom daily or weekly for maintenance. This need to be part of your trading systems.

They do send regular e-mails about this. Here is the last one i got:

The Demo server will be rebooted every day this week at approximately 6 PM EST/EDT. This can take up to five minutes to accomplish. We will have it back up as soon as possible.

Thank you,

IBFX

Also if you really need to know why they do this is best to ask them. Why do you expect to get an accurate answer about this here?

Because I expect someone here to be very familiar with IT to say, 'yes, resetting servers is not something that should have to be done so often. Servers can easily run for months without problems." Or for them to say, "Servers can have a difficult time blah blah blah blah and need to be reset periodically."

I don't want to hear excuses from my broker.
