Gomvents, this is very different from "forfeiting rights". In any case this does not appear to be from the Adsense TOS. The equivalent section there is:

8. No Guarantee. Google makes no guarantee regarding the level of impressions of Ads or clicks on any Ad or Referral Button, the timing of delivery of such impressions and/or clicks, the completion of Referral Events, or the amount of any payment to be made to You under this Agreement. In addition, for the avoidance of doubt, Google does not guarantee the Program will be operable at all times or during any down time (i) caused by outages to any public Internet backbones, networks or servers, (ii) caused by any failures of Your equipment, systems or local access services, (iii) for previously scheduled maintenance or (iv) relating to events beyond Google’s (or its wholly owned subsidiaries’) control such as strikes, riots, insurrection, fires, floods, explosions, war, governmental action, labor conditions, earthquakes, natural disasters, or interruptions in Internet services to an area where Google (or its wholly owned subsidiaries) or Your servers are located or co-located.

9. No Warranty. GOOGLE MAKES NO WARRANTY, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION WITH RESPECT TO ADVERTISING, LINKS, SEARCH, REFERRALS, AND OTHER SERVICES, AND EXPRESSLY DISCLAIMS THE WARRANTIES OR CONDITIONS OF NONINFRINGEMENT, MERCHANTABILITY, AND FITNESS FOR ANY PARTICULAR PURPOSE. TO THE EXTENT ADS, LINKS, AND SEARCH RESULTS ARE BASED ON OR DISPLAYED IN CONNECTION WITH NON-GOOGLE CONTENT, GOOGLE SHALL NOT HAVE ANY LIABILITY IN CONNECTION WITH THE DISPLAY OF SUCH ADS, LINKS, AND SEARCH RESULTS.

10. Limitations of Liability; Force Majeure. EXCEPT FOR ANY INDEMNIFICATION AND CONFIDENTIALITY OBLIGATIONS HEREUNDER OR YOUR BREACH OF ANY INTELLECTUAL PROPERTY RIGHTS AND/OR PROPRIETARY INTERESTS RELATING TO THE PROGRAM, (i) IN NO EVENT SHALL EITHER PARTY BE LIABLE UNDER THIS AGREEMENT FOR ANY CONSEQUENTIAL, SPECIAL, INDIRECT, EXEMPLARY, OR PUNITIVE DAMAGES WHETHER IN CONTRACT, TORT OR ANY OTHER LEGAL THEORY, EVEN IF SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES AND NOTWITHSTANDING ANY FAILURE OF ESSENTIAL PURPOSE OF ANY LIMITED REMEDY AND (ii) GOOGLE'S AGGREGATE LIABILITY TO PUBLISHER UNDER THIS AGREEMENT FOR ANY CLAIM IS LIMITED TO THE NET AMOUNT PAID BY GOOGLE TO PUBLISHER DURING THE THREE MONTH PERIOD IMMEDIATELY PRECEDING THE DATE OF THE CLAIM. Each party acknowledges that the other party has entered into this Agreement relying on the limitations of liability stated herein and that those limitations are an essential basis of the bargain between the parties. Without limiting the foregoing and except for payment obligations, neither party shall have any liability for any failure or delay resulting from any condition beyond the reasonable control of such party, including but not limited to governmental action or acts of terrorism, earthquake or other acts of God, labor conditions, and power failures.
