Dear customer,

We are currently experiencing degraded performance on some instances located on the Virtual Server platform in Germany.

We are investigating the issue and as soon as we have more information available, we will publish it here.

[Update 13:10]
The performance is slowly increasing again but we are still busy with our storage vendor to further troubleshoot the issue. Once more information is available we will update this post.

[Update 14:35]
The performance issue has been solved and everything is back to normal again.

If you still encounter any performance related issues please contact our support department at [email protected].

Dear LeaseWeb Customer,

Currently we are experiencing reachability issues from certain locations to certain locations. We are currently investigating the cause of this problem and will update you once we have more information.

Update at 13:56
The issue has been resolved now. It was caused due to a major fiber cut at our provider that caused internal routing complications. We surpassed the issue by changing the routing policies.

Dear LeaseWeb Customer,

LeaseWeb learned today that it's network has been added to the UCEprotect blacklist. This means organisations using UCEprotect as part of their spamfilter will block email sent from a LeaseWeb IP-address, even if your IP-address or IP-range has never sent spam in the past.

Unfortunately we were not notified about the listing by the blacklist owner however we have already taken proactive measures to eliminate the source of this listing and we are currently working very hard to get the listing issue resolved permanently.

LeaseWeb has a well known zero tolerance policy for spammers within it's network. We are committed to the eradication of spam and 'badware' from the internet. For this we have established our 'Community Outreach Program', of which a multitude of blacklist are part.

We take your trust in us very seriously. The abuse handling team is working very hard to resolve this issue. We apologize for any inconvenience and we will continue to update our NOC page as we have any further updates.

If you need further information, please open a ticket via the LeaseWeb Self Service Center, or contact us at [email protected].

[Update]
The UCEProtect website shows that our AS has been delisted from their blacklist. This means that email from LeaseWeb IP addresses is no longer blocked by those who use the UCEProtect blacklist to filter spam.

We are still trying to reach out to UCEProtect, to prevent this from happening in the future.
