title: Compute Engine Istance group gcloud - IP change if a specific istance go down
body: <p>I have a huge problem with the manage of an istance group on gcloud compute engine.</p>
  
  <p>I setting to the 1st istance of the group a static ip XX.XXX.XX.XX, this ip is connected with a Domain.</p>
  
  <p>If during the scaling the first machine created was canceled, no one of the new instances will take that IP.
  This is a problem because my domain go down.
  I thinked to manage this by creating another separeted istance that ping the domain...and if the domain is down change (with gcloud commands) the ip of one that new istances.</p>
  
  <p>I want to ask, there is someone that had found some trick to solve this issue? 
  Thank's guys</p>
  
  <p>EDIT: Ok, LB is working, but I need to "live streaming" through that LB because this LB manage an istance group that manage the live streaming.
  Now, if I set it, I can't go live (from any software, such OBS and similar) :/</p>
  
  <p>So, a little recap:
  I have my domain <code>example.com</code>
  I have my istance group <code>istance_group_example</code>
  Load balancer <code>http_loadb</code>
  I set on the frontend of http_loadb my ip (static, not temp), then I go to cloudflare and set the static ip.
  If i go to my example.com, i can see my custom page.</p>
  
  <p>Now the problem is, i can access to server, but if I need to create a live streaming with OBS (for example), obs just load the connection for a while but then stop. </p>
  
  <p>If i point my DNS directly to the IP of an istance inside istance group (bypassing the load balancer) everything works.</p>
