Some systems are experiencing issues
Active Incident
DDoS attack on SEO router
Status: Watching - 22 hours, 34 minutes ago

We are currently experiencing a DDoS attack on one of our SEO routers. Technicians are working on resolving the issue.

Updated 22 hours, 12 minutes ago
Status changed from Investigating Identified

New information:

The issue has been identified since a while ago, a temporary fix has been applied by blocking all UDP traffic except for DNS UDP traffic for port 53.

Because it's such a large distributed attack and since there is no common denominator there is no way to block all the attackers source traffic. We are monitoring to see when the attack stops and at that point we can start allowing UDP traffic again.

Status changed from Identified Watching

New information:

The attack is still ongoing, we are constantly monitoring the situation and will unblock all UDP traffic when it has stopped. We are sorry for any inconvenience this might cause you.

If you have a urgent need to use other UDP ports than DNS please contact our support at support@crystone.se and we can look at opening it for you.


Maintenance of Hosting panel & order/billing
Status: Fixed - 6 days, 8 hours ago

On Thursday morning we will perform some minor updates to our automation and billing systems, causing the control panels and order pages to be unreachable for around 30-60 minutes starting at 5 am. This will not affect any of the customers services (web, dns, email etc).

The update is for fixing minor bugs, and mainly to prepare coming updates to UI and features.

Update 06:20 The work is finished and all systems are open again (a bit later than planned, apologies)
