Two related questions:
1) If the Internet connection is lost, will the Hub need to be reset? Will this also require re-pairing devices to the Hub?
2) First, assumptions and understandings: With a few exceptions for additional devices, the system uses z-wave and Zigbee to communicated between devices (e.g., Door sensor may pass through the SmartSwitch to amplify the signal), not WiFi. The internet connection is used to (a) Update the Hub and (b) Communicate with the Web and Mobile interfaces for management and alerts.
- Question: If using a Utilitech Indoor siren, which communicates via Zigbee or z-wave, does the siren operate if a sensor is triggered when the Internet connection is down? (If not, I'm assumming that this functionality would have to have been programmed out in the Hub to sell monitoring and 3G/4G modems.)
Look forward to a response before testing...I've heard of issues wiht the Hub when the Internet is down, so looking for an answer online first.

To answer your questions:
1. The hub doesn't need to be reset if you lose your home internet connection; as soon as your broadband connection returns, the hub will automatically re-connect to the Iris cloud platform. There's no need to re-pair devices or reset anything.
2. Your assumption is correct; and as you might guess, with the local alarm processing that is part of Iris, even if the hub's broadband internet connection is offline, if your alarm was armed and triggered (by say a contact sensor opening) the siren (which is Z-wave if you are curious) will sound locally.
Hope this helps,
This subject may need some furhter clarification: how fast does the hub detect the loss of the internet connection only, as opposed to the power loss? In the former case, the router is still up and there is a local LAN signal to the hub, but no outside WAN connection, is that detected as fast as the total loss of the network signal in the case of power out (= router off)? The question is quite relevant because if a burglar cuts the internet cable at the back of your house, it can be literally seconds before the break in.
The hub will detect the loss of network connectivity within a few seconds. You can test this for yourself - unplug the WAN cable on your router, and you will see the red light start to blink on the hub as it detects the loss of its connection to the Iris cloud.
