So things should be better soon. I have also mailed all 500+ TCB members about the temporary problems.
We have been having difficulties with server 10 lately, which are on our end.
We apologize for the inconvenience, but please rest assured that this is a temporary situation and will be corrected shortly. We are currently working to load-balance our servers which will allow non-busy servers to pick up the slack when load on your server becomes high. This will improve website speed and reliability for all customers across-the-board.
Please note that things should improve for your site before the servers become load-balanced, but once they do become load-balanced this should certainly not happen again.
Thank you for your patience.
