Last night (17 August) we successfully migrated all Burst SMS and Reseller accounts to new more powerful servers. You should notice a significant increase in general site performance especially when loading pages with lots of stats like the ACTIVITY screen and REPORTS.
We have been notified of some browser specific issues recently especially around IE9 and Google Chrome. Please note that the new servers will not fix this, but we are working as fast as possible to upgrade all areas of the site to be compatible with IE9. In the meantime we suggest using Firefox or Safari.
If you encounter issues at any time please email email@example.com
