During a routine renewal of Kerio's SSL/TLS certificates the server did not automatically reboot. After manually restarting Kerio all services are running smoothly again. No further downtime is expected.
We are experiencing reduced deliverability for outgoing e-mails sent through our our mail-filter to specific providers such as Microsoft (@outlook,@live,@hotmail,@office365) and Yahoo (@yahoo) due to a blacklisting. We are investigating the cause and taking actions to resolve this issue.
We have determined that the issue was caused by spambots abusing a large amount of unprotected webforms of our clients. We have contacted these clients and asked them to resolve the problem on their websites. We have also contacted Microsoft and Yahoo to delist our IP-addresses from their blacklists. Microsoft has confirmed they will delist our IP-adresses within 24-48 hours. We are still waiting for a response from Yahoo.
Since 13:10 we no longer see mail deliverability issues for mails sent to Microsoft. Mails sent to Yahoo remain throttled. We are still waiting for their response in order to fully resolve the issue.
We are still seeing Yahoo throttling mails sent through our platform. In order to work around this we will be adding additional IP-addresses to sent these e-mails. Yahoo remains very restricted however, and a definitive solution will require their cooperation.
We are seeing significant improvements in mail deliverability to Yahoo. We are still monitoring the situation.
No further deliverability issues have been observed. The incident is resolved.
Between 09:25 and 09:35 our monitoring detected a degradation of the DNS performance. This degradation was caused by a DDoS attack. As of 09:35 the query performance has been restored. We are monitoring the situation for any possible new attacks.
DNS continues to be working as expected. The incident is resolved.
We're seeing reduced availability of the DNS platform resulting in DNS queries not receiving an answer.
We've seen a spike in traffic due to a DDoS. This resulted in reduced reachability of services like our DNS platform and thus failing DNS queries. The attack has been mitigated for now but we're closely monitoring the network traffic for deviations.
We're no longer seeing DDoS traffic and all services work as expected.
