If you use them & your images go down, don't start freaking out as they are moving servers.
And we all know how smoothly server moves can go so don't be surprised if it takes a while longer than that.On April 7th 2015 between Midnight and 09:00 EDT, a relocation of our servers will be performed. Service may be interrupted during this period.
Edit: I was also told on another forum that if you use imgbox, they are also doing the same thing at the same time.
I guess they either own both of the imagehosts, or they are on the same servers.
