Yes, it's happening again. But in a different way. If the site doesn't load, or if it times out while you are posting, try again later.
Some members have not been able to get the site to load at all, never mind posting. Some have failures then it goes back to working, for no apparent reason. Some of us have had no interruptions in service whatsoever. There are a variety of things causing the problems.
Part of it is that sections of the Intarwebs were broken yesterday, and have not fully recovered. People on Verizon and L3 were particularly having problems, resulting in direct traffic to sites being detoured and rerouted around the broken areas - slowing everything way down. This delay in the signal also led some people who could get on to the site to have their sessions time out while they were trying to post. If the Internet has been slow for you in general over the last few days, this is probably what's affecting your connection.
We can't fix the parts of the Internet that other people broke. We are looking to see if there's anything we can adjust with our servers or interface that could compensate for this slowdown and resultant missed connections. It's been slow going. Like putting balloons on your mailbox to help people find your house when actually the bridge on your road is closed.
As those of you who've been here for a while know, we have had to move the site a number of times. Adjusting to new servers, upgrading software, and then the DDOS attacks have caused us a variety of problems. The tech team is on it. You all have our sincere apologies and shared frustration in this.
