NEPAL TELECOM : : WEB-SMS down on load shedding ?

If you are registered user of Nepal Telecom, you can use the web-sms service for free!
However there is limitation of 10/20(?) message per day. Fair enough.
But...
Many of the times, I attempt and I can not access the web sms service of Nepal Telecom.
Some of my friends suggested that the towers and hence the service of Nepal Telecom is down whenever there is Load Shedding. Because the towers do not have generators.
Simple!
No service.
There is no customer service awareness, just live in dark and wait for the lights to come.

As written on http://websmsnew.ntc.net.np/websmss/:
The Short Message Service (SMS) is the ability to send and receive text messages to and from mobile telephones. The text can comprise of words or numbers or an alphanumeric combination. SMS was created as part of the GSM Phase 1 standard. Each short message is up to 160 characters in length when Latin alphabets are used, and 70 characters in length when non-Latin alphabets such as Arabic and Chinese are used. When a mobile user sends SMS to other mobile user, the message is at first sent to SMSC server which then stores and forwards the message to respective destination.

Web-SMS is a new web based service launched by Nepal Telecom in order to facilitate its valued customers. Valid Nepal Telecom mobile or internet subscribers can register to this service and send SMS to Nepal Telecom mobile users. You do not need to own mobile for using this service.

There is nothing stated about load shedding, in ideal world there would be no such thing as load shedding. (Sounds Funny?)
