UptimeRobot, which I have been a happy user of since 2010, has been failing me in the last months, reporting hundreds of false downtime alerts for my 34 websites monitored by them. Since beginning of March it has been particularly bad with 20-30 false alerts per day.
I tried to get in touch via Twitter and email a couple of times but received no response so it was time to say goodbye.
@uptimerobot I have been getting wrong downtime alerts since March 3. Any changes in your setup?— Manuel Meurer (@manume) March 6, 2014
