When Twitter is over capacity and the “Fail Whale” error message signals another Twitter outage or slows to an elephant crawl, it’s not a surprise to many Twitter users anymore. Over the years, Twitter performance has struggled to handle its rapidly growing capacity. Interestingly, the “Fail Whale” was originally drawn featuring an elephant (not a whale) in 2002 by an China-born artist named Yiying Lu.
Downtime events like the Sept 27, 2012, PNC Financials website outage make for compelling headlines, banker headaches, and bank website user annoyances. But, is this downtime more than that? Is it another locus-of-control (digital access to money) in the modern age that is spinning out-of-control into an encroaching cyber black hole of economic chaos? Well no, but… downtime and slow downs do have an impact.
Dotcom-Monitor is tracking the current Wells Fargo Bank outage as well as a reported US Bank outage and PNC outage.

The GoDaddy DNS outage and Paternity Test: Who’s your GoDaddy? Its another episode of the Maury Povich Paternity Test on DNS Outage TV yesterday. Having just written about a major AT&T DNS outage on Aug. 15, here we are again on Sept 10, 2012 witnessing the GoDaddy DNS outage. Millions of website and email users DNS look-up process is playing out like a Maury Povich TV episode of paternity testing gone wrong. First time visitors to a GoDaddy website type the GoDaddy URL into their browser and the answer from the DNS comes back “This aint your GoDaddy.” Or something like that.
To Cache or Not-to-Cache – that is the DNS Monitoring Question
Firstly, it is not generally well-known that external-based HTTP request-type website monitoring, like coffee at your local java joint, comes in different “grades” – cache-based and non-cache based. Dotcom-Monitor employs non-cached monitoring, which propagates through the full DNS process with each monitoring instance. Cache-based monitoring (used by many basic monitoring services) does not propagate through the DNS process and misses DNS issues.
How to Effectively Monitor for the next DNS Outage Situation
In the case of the AT&T DNS outage issue there are several key factors that help to speed up Time-to-Repair (TTR), or avoiding downtime.
