Once you enable MyDomain, all URLs change from the POD-specific ones to be MyDomain-specific. Is there any easy way to find out the POD the Org is running on without contacting Salesforce?

If you are looking for Host URL following line will return full host url.
System.URL.getSalesforceBaseUrl().getHost()
If you are looking for instance on which your org is hosted then use following link
