  Good morning all ,

  I have an alwayson instance with a multisubnet listener

  I configured RegisterAllProvidersIP = 0 in order to register a single DNS entry

  HostRecordTTL is configured at 1200 seconds

  I would like if with this configuration I will have timoeout during the failover

  if so how much time is needed for the application to connect to the lsitener

  thanks

  DNS is the attributing factor here, you need to ask your domain/network admins what the sync time is for your environment.

  So take that time, plus up to around 40 minutes depending when your clients last updated from DNS

  40 + DNS Sync Time = up to X minutes before reconnection
