From the hosting company I use for signature logos:
"We will be performing system maintenance that will impact your service on Wednesday, May 16th, 2018 between 7pm and 9pm Arizona Time (02:00 and 04:00 UTC May 17th, 2018)
Shared Web Hosting Web Sites
Virtual Private Servers
During this maintenance window services will be intermittently unavailable.
This maintenance is to upgrade network storage systems to increase performance.
Omnis Network, LLC "
So, if you have a logo and it doesn't appear next Wednesday, fear not... it's just a temporary condition.
Like Arnold: It'll be back!
