Site won't load after purchasing larger MySQL database

Hello All:
I have my WordPress 4.2.2 site running on Azure, with a MySQL back end database. That db was getting full so I purchased a larger plan (250 Mb).
I made the following changes in Azure Configuration:
* Added a new linked resource to the new MySQL db
* changed the one ConnectionString, including the name, to reference the new db with new credentials.
I changed the wp-config.php file via WebMatrix to update the four entries for DB_NAME, DB_USER, DB_PASSWORD, and DB_HOST as appropriate.

Using MySQL Workbench I can log into the new database. The site was working after this switch as an edit in the site yielded a new data row in one of the tables. So I DELETED the old MySQL database and the associated Linked Resource entry in Azure

Also, unintentionally, the hosting plan in Azure switched from SHARED to FREE, then right back to SHARED.

Now my site won’t load. I’m not sure if it’s because of the DB changes, or incorrect Config settings or Azure Hosting Plan getting cycled. I have verified that the IP address is still the same and everything looks right there and at the Domain Name Registrar site.

Not sure where to look.
Any help would be appreciated.

Thanks in advance.
