How reliable are network operations of cBot?

Hello Spotware Team,

how reliable are the synchronous network operations a cBot can perform like ExecuteMarketOrder(), PlaceLimitOrder(), ModifyPosition(), ModifyPendingOrder(), ClosePosition() and Positions()?

If the server doesn't respond because it is temporary overloaded/down or cTrader Desktop has temporary network issues, will the running cBot perform internally some retry operations and what is the exact retry logic? Or will it fail on first network/server problem? 
Is there any difference in synchronous and async cBot operations regarding this issue?

Thank you!
