From the host:

I just got notified that there may be a brief outage tonight around midnight CST as The Planet replaces the MUX that caused the outage yesterday morning. As many of you have noticed, the speeds haven't been the same since that outage as apparently the piece that was put in place to solve the problem, isn't sync'ing up properly.

Around midnight tonight they will be replacing this part which may cause an outage on the HE.net and Yipes lines. There's a chance that they can migrate them over without downtime, specially on the HE.net since we have multiple links to them; but it is very likely that Yipes will see a full outage for a period of 10-20 minutes.

Hopefully this will be the end to our recent problems. I have made sure that their chief Network Engineer is going to be present during this to oversee that this process goes through smoothly.
