Check Backups to be sure that they are running smoothly...
- Train your coverage staff on items they will need such as:
- - A refresher on the servers, and how to access them
- - Any required passwords (or a password database)
- - A list of vendor contacts for specific systems and areas
- - Any specific procedures, such as how to on-board a new staff member, how to set up email, how to administer the spam filter
Check your vendor contracts to be sure none require renewal while you are out, some vendors are very hard to deal with if you miss the renewal date (Citrix)
Make plans for how or if you will be reachable during your vacation.
I advocate disconnecting as much as possible, but if you are going to be in touch consider the network costs if you are traveling. You can use Skype, Google Hangouts, or Facetime to stay in touch if you have a Wifi connection at your destination. Your peeps at home can peep! You can share video if they have a computer and a camera.
Be careful with outrageous international coverage rates and even worse data roaming charges if you plan to leave the country. If you are leaving the country it is probably best to shut down your cellular network and only use Wifi. If you are traveling out of the country for a long period, and you want to be reachable it may be easiest to get a SIM card or a temporary phone when you arrive. One good recent feature in gmail, google voice and also in Outlook is SMS to email conversion. You could be able to text people from your email, without the cost of SMS messaging.

So now I am back from Europe, and a quick comment on travel network access. First, weird fact, in France and Spain Wifi is pronounced "Wiffy". I found that Skype was great, but even more so I set up my T-Mobile cellphone on Wifi calling. Text messages and telephone calls went out over the network for free, as I had disabled the cellular network. Text to my Google voice number translated into my email, and that was also helpful. But there were definitely times I could have used a local cell phone. Pretty good overall.
