Are broker glitches possible?

I am 8 months old in trading forex and was wondering if there is a possibility of price glitches happening at the end of the brokers ? Due to some glitch price would move 100 - 1000 pips in a second, etc etc

I personally have never experienced anything like that but was wondering about how good their softwares would have to be to prevent price to fluctuate drastically due to some error.

Thoughts ?
