Do IP and/or DNS changes impact Paid search (Adwords, Bing, etc.)

[MWM3772]

What impact (if any) does IP or DNS changes, have on paid search campaigns?

We recently performed an upgrade to our sites that required a datacenter change (but within the same region East US)  and DNS change.  We believe there may have been an impact to our ad campaigns in the form of suppression of our ads following the change, specifically - Google Adwords.

Is there any information regarding this issue or has anyone experienced this before?

Thanks

I have never seen any impact on PPC when migrating a site to a new server relating to the IP/DNS changes.

If the migration didn't go as planned and the new server returned 404, 500 or similar, however, you would find Google may stop serving ads if it noticed. You would receive a notification in Google Ads if that was the case tho.

Why do you believe that your ads were being suppressed?

Thank you for the response.

We started to see in the Adwords console,  Ads previously approved and running were not being shown and we could not tell why.  By the latter half of the next day things were back normal.

All we could think of,  was perhaps the DNS/IP changes  created the need for Google to pause the ads and re-validate the domain.
