We have closed down GIGRIB due to our continued commitment to the Pingdom uptime monitoring service.
Pingdom is a far more full-featured monitoring solution and doesn't require you to install anything. We hope you will consider it as a better alternative to GIGRIB. Pingdom has both free and paid options.
To those of you who have previously used GIGRIB, thank you, and we hope we will see you join us on the Pingdom service!
