18.104.22.168 was partially unavailable because of an erroneous BGP blackhole configuration update by an ISP that was propagated by a Tier 1 provider. Note that our users who were using other IP addresses like 22.214.171.124 still could use the service. The error has been resolved and 126.96.36.199 has resumed normal operation.
