Last updated November 13, 2025.
PREAMBLE
Professional Wiki GmbH (‘Professional Wiki’, ‘we’) provides managed hosting of MediaWiki instances (‘Wikis’) for customers (‘Customer’). This Service Level Agreement (‘SLA’) sets the service availability and support targets for the Wikis we host (the ‘Service’).
1. DEFINITIONS
The following terms, as used herein, have the following meanings, whether used in the singular or plural (some terms are defined within the section in which they are used):
- “Wiki” means a MediaWiki instance hosted by Professional Wiki for a Customer.
- “Service” means the managed hosting of Wikis and related support provided under this SLA.
- “Service level” means standards Professional Wiki adheres to and by which it measures the level of Service it provides as specifically set forth below.
- “Working hours” are defined as 9.30am-5.30pm Monday-Friday in the timezone of Professional Wiki’s head office (Berlin, Germany, UTC +1h or +2h), excluding public holidays at Professional Wiki’s head office.
- “Minimum availability” means making the Wiki available to the Customer at a rate of at least 99.0% of the respective calendar month. In this context, the Wiki is available if there is an uninterrupted connection between the servers on which the Wiki is hosted and the transfer point to the Internet and the Customer is able to log on and access the Wiki. The minimum availability does not apply to test and development servers. Unavailabilities rated as Critical (see ‘Levels of Unavailability’) apply.
1.1. EXCLUSIONS
This SLA and any applicable Service Level do not apply to any performance or availability issues:
- Hardware and connected services such as third party APIs or data delivery through third-party-networks;
- Due to factors not foreseeable and/or outside Professional Wiki’s reasonable control;
- Due to external factors i.e. not related to the Wiki or Service;
- That resulted from Customer’s or third-party’s hardware or software;
- That resulted from actions or inactions of the Customer or third parties;
- Caused by Customer’s use of the Service after Professional Wiki advised Customer to modify its use of the Service, if Customer did not modify its use as advised;
- During scheduled downtime; or
- During beta and trial services.
This SLA does not apply for recovery procedures caused by the Customer deleting or removing data by accident.
2. SERVICE LEVELS
- “Critical Functionality” is defined as a functionality that is critical for ensuring the Service required by the Customer. The critical functionalities in the context of this SLA are: minimum availability of the Wiki. Problems linked to a specific user, a specific user account are not considered as Critical Functionality.
- “Downtime” is defined as any period of time when the Customer is unable to use a Critical Functionality for all its users. The Downtime is calculated using Wiki availability in minutes. The Downtime must be reported in English by the Customer with an email to [email protected] (see section “Issue Reporting”) to be taken into account. Downtime does not include the period of time when the Services are not available as a result of:
- Scheduled Downtime or scheduled network, hardware, or service maintenance or upgrades; or
- the acts or omissions of the Customer or the Customer’s employees, agents, contractors, or vendors, or anyone gaining access to the Services; or
- Customer requested changes;
- third party’s actions or inactions; or
- a case of Force Majeure.
- “Force Majeure”. Any Downtime in Services or Critical functionalities will not be considered a breach of this Agreement if and to the extent caused by events beyond Professional Wiki’s reasonable control, including, but not limited to, acts of God, embargoes, governmental restrictions, strikes, lockouts, work stoppages or other labor difficulties, riots, insurrection, wars, or other military action, acts of terrorism, civil disorders, rebellion, fires, floods, telecommunication stoppage, vandalism, or sabotage (“Force Majeure”). Professional Wiki’s obligations hereunder will be suspended to the extent caused by Force Majeure so long as the Force Majeure continues.
- “Scheduled Downtime” is defined as:
- Downtime within scheduled maintenance windows. The notice is two working days in advance; or
- Downtime of less than ten minutes.
- Cumulative monthly Scheduled Downtime should not exceed 4 hours. Scheduled Downtime is not considered Downtime for purposes of this SLA. Professional Wiki announces Scheduled Downtime via email or at the dedicated web page accessible on our website.
3. ISSUE REPORTING

| Major | Received by email (T0) | 92 h | 172 h |
| Minor | Received by email (T0) | 12 weeks | 12 weeks |

5.2. MISUSAGE
