It has been over a month since the Blogger custom domain function encountered problems just a few days after its launch. At that time, when this feature was first introduced, quite a number of internet users must have registered numerous domains and spent a fair amount of money. However, in response to this "unfathomable" service interruption, apart from feeling heartbroken, there was nothing much one could do about it.

Nevertheless, at 15:24 Beijing Time today, I suddenly found that ghs.google.com is pingable again.

Just to mention, I am with Hubei Telecom.
