Would you like to help for me with great correction for the my short essay?
The domain name servers of GB Bank were working in their own data center. I implemented a new domain name server which is located on the cloud. During that implementation, I got a failure related to some dns records of the yahoo server. Some customers of the bank could not send email to GB Bank using the Yahoo email. Those emails are very critical and hurried because those people are employee's sending salary information. That condition was very tricky, almost all of them calling over the phone and telling our employees about the salary of this month.
I have created users for those users on a shared server and suggest they upload on it. Then I received those data and passed all of them to the accountant of the bank. then the problem is solved. Also I fixed the wrong dns record.
