When GoogleApps is Inaccessible

The following question was recently posted to the Google-Certified-Teachers list, and since it echoes recent experiences of my own, I thought I'd share it:
Can anyone help advise what to do. We are suddenly unable to send mails from our gafe accounts
We keep getting the error bellow.
Our domain hosts say the problem is not by them... Has anyone got some advice?
Many thanks
DNS Error: Timeout while contacting DNS servers
Technical details of temporary failure: 
Here is my response, which I typed up on my mobile phone using @CloudMagic, a great email app for Android and iOS devices, but have edited a bit for readability:
Your domain servers house the info that identify your organization to GoogleApps. If Google cannot connect to them, you will be unable to send or receive email. 
In my recent experience, this is caused when your domain servers has 1) Failed, 2) They cannot be reached via the web, perhaps your internet service provider is offline. 
If you still have internet then it is prob #1. If your server and network are ok but no internet it is prob #2. There may be other reasons but try to investigate those of two.
A third suggestion was offered by another list member; that suggestion was that the MX records are no longer correct. For those that may not remember what an MX Record is...
mail exchanger record (MX record) is a type of resource record in the Domain Name System that specifies a mail server responsible for accepting email messages on behalf of a recipient's domain, and a preference value used to prioritize mail delivery if multiple mail servers are available. The set of MX records of a domain name specifies how email should be routed with the Simple Mail Transfer Protocol (SMTP). Source: Wikipedia
What other suggestions would you offer?
