Updated Feb. 10, 2019 08:18:28 Google issued a DNS update that temporarily removed the DDoS protection on its DNS servers in response to a large number of requests that began to flood the network.
The company said it is taking steps to improve DNS service in the coming days, including making the DNS server addresses available to all sites and allowing those who are experiencing DNS issues to use the public internet instead of using the internal DNS servers.
The DNS update also includes a small tweak to the default settings that allows a site to show up on its homepage for users who are visiting from outside the U.S.
The change, first spotted by Ars Technica, is the result of a surge in traffic on Google’s DNS servers after a string of DDoS incidents that were believed to be linked to a Chinese company called GreatFire, which is believed to have orchestrated several of the attacks.
Google confirmed to Ars that the DNS update does not apply to GreatFire-related domains.
Google said it has deployed an automated system to block the malicious DNS requests.
The system currently blocks requests made to all Google.com domains, but it may block other Google domains in the future, according to the company.
In the meantime, those who want to use Google’s internal DNS service should update their accounts to the newest version, according a Google blog post.
The company is also expanding the number of domains that can be accessed from the internal servers to allow users to browse the Google DNS database.
Google has also introduced a new option for its users to request DNS updates from its internal servers.
A new check box is added to the top of each Google homepage page that allows users to update their settings.
Users can also choose to manually update their DNS settings for their own sites by visiting the Google Settings page.
