E Street does most of its server and network maintenance on Sundays. The time varies depending on the length of the job and available manpower. If you notice times when a specific server or service is not available, and it is Sunday, we are probably doing maintenance.
Any repair or maintenance that will effect our main connection to the Internet will be scheduled and announced well in advance. Most of that work is done between Midnight and 4:00am.
If you have questions or concerns, contact <support@estreet.com>.
