We get alerts from time to time that SharePoint and Skype Websites might not be loading correctly or not at all. The following is a script that will generate a report, with time and date, showing the availability of the websites in question and the time it takes to load them.
First off, you want to create a text file called URLList.txt that will have the list of websites you want to check. I save the file in the C:\PowerShell directory but you can change the path to where you need it. If this happens often, having this list prepared will help you evaluate the environment quickly and allow you to troubleshoot if necessary efficiently.
Here is the script:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 | ##WebsiteChecker.ps1 built by Lance Lingerfelt - LDLNET LLC - Life In Action!
