Ответственность сторон определяется заключенным договором
Естественно. И по большинству договоров на софт - никто не несет никакой отвественности, в особенности крупные компании типа MS, IBM и т.д.. Даже, если вы платите деньги за софт
Или вы ни разу не читали ни один EULA, а просто тыкали птичку, мол, согласен со всем?
А у западных хостеров договоры встречаются и такие, что хостер ответственности не несет вообще никакой, а клиенты несут ответственность, например, за случайное повреждение оборудования в дата-центре при визите туда, а для обеспечения платежеспособности от клиента требуется предоставить страховку на случай нанесения ущерба третьим лицам в размере до 1.000.000 USD
Не хочет клиент нести ответственность - в его праве выбрать другого хостера.
Возьмем к примеру договор на софт с Akamai:
7. Disclaimers.
The Software is provided "AS IS" basis without warranties of any kind, either express or implied. Akamai discloses all warranties express and/or implied warranties, including, but not limited to, warranties of merchantability, fitness for a particular purpose, noninfringement and title, and any warranties arising from a course of dealing, usage, or trade practice. The duration of any implied warranty that is not effectively disclaimed will be limited to the warranty period. Akamai does not represent or warrant that the Software or materials provided through use of the Software are accurate, complete, reliable, timely, secure, current, or error-free.

8. Limitation of Liability.
(a) You expressly acknowledge and agree that in no event shall Akamai, its officers, directors, shareholders, affiliates or licensors be liable for any special, punitive, incidental, consequential or exemplary damages, including but not limited to damages for loss of use, computer failure or malfunction, loss of goodwill, lost profits, loss of data or information, unauthorized access to and/or loss of your personally identifiable information, or any and all other commercial damages and losses, arising out of or in connection with the Software or its use or this Agreement, even if Akamai, its officers, directors, shareholders, affiliates or licensors have been advised of the possibility of such damages. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you. (b) Akamai is not responsible for any problems or technical malfunction of any telephone network or lines, computer online systems, servers or providers, computer equipment, software, failure of any email or players due to technical problems or traffic congestion on the Internet or on any the Software, including any injury or damage to users or to any person’s computer related to or resulting from participation or downloading materials in connection with the Software. Under no circumstances shall Akamai be responsible for any loss or damage, including personal injury or death, resulting from use of the Software or from the conduct of any users of the Software, whether online or offline. (c) You acknowledge and agree that the provisions under this Agreement that limit liability, disclaim warranties, or exclude consequential damages or other damages or remedies are essential terms of this Agreement that are fundamental to the parties' understanding regarding allocation of risk. Accordingly, such provisions shall be severable and independent of any other provisions and shall be enforced as such, regardless of any breach or other occurrence hereunder. Without limiting the generality of the foregoing, you agree that all limitations of liability, disclaimers of warranties, and exclusions of consequential damages or other damages or remedies shall remain fully valid, effective and enforceable in accordance with their respective terms, even under circumstances that cause any exclusive remedy under this Agreement to fail of its essential purpose.
Это я к тому, что если Akamai (как хостер) ничего не гарантирует, то смешно будет смотреть, как кто-то другой будет гарантировать 
Про фарадея раскажите детям, честное слов

The answer is that they produce cosmic rays, which produce high energy particles in the atmosphere that can occasionally hit RAM chips. The moving particles trail electrons, which can infiltrate chips' circuits and cause errors.

However, their own research indicates that most errors in dense SRAMs are due to cosmic ray events.
