Chess 2's DNS service No-IP issued a statement regarding the takedown, noting that Microsoft seized 22 of its domains after finding evidence of malware creators distributing harmful software from its subdomains.
"We have been in contact with Microsoft today," No-IP reports. "They claim that their intent is to only filter out the known bad hostnames in each seized domain, while continuing to allow the good hostnames to resolve. However, this is not happening. Apparently, the Microsoft infrastructure is not able to handle the billions of queries from our customers. Millions of innocent users are experiencing outages to their services because of Microsoft's attempt to remediate hostnames associated with a few bad actors."
