    In re: Keith T. DOUGHERTY, Petitioner.
    No. 10-3253.
    United States Court of Appeals, Third Circuit.
    Submitted Pursuant to Rule 21, Fed. R.App. P. Aug. 19, 2010.
    Filed: Sept. 10, 2010.
    
      Keith T. Dougherty, Harrisburg, PA, for Petitioner.
    Before: BARRY, FISHER and GREENAWAY, JR., Circuit Judges.
   OPINION

PER CURIAM.

Keith Dougherty, proceeding pro se, filed in the District Court a complaint under 42 U.S.C. § 1983. After attempting to serve process on several defendants and receiving no answer to his complaint, Dougherty filed three motions — all within eight days of each other — requesting that the District Court enter a default judgment pursuant to Federal Rule of Civil Procedure 55 against the defendants. The first of these motions was deleted from the docket as improperly filed. Eight days after Dougherty filed his first Rule 55 motion, the District Court denied his requests, reasoning that Dougherty had not properly served the defendants. Dougherty unsuccessfully sought reconsideration and then filed a petition for writ of mandamus. He requests that we direct the District Court to enter a default judgment against the defendants and that we compel Judge Caldwell to recuse himself. Dough-erty also filed a motion to supplement the record, to which he attached a copy of the District Court order denying his motion to reconsider his request for a default judgment. Liberally construing his pro se filings, we construe his inclusion of the order as a challenge to the order denying reconsideration.

Mandamus is an “extraordinary remedy” that we award only when a petitioner demonstrates, among other things, a “clear and indisputable” right to relief. In re: Pressman-Gutman Co., 459 F.3d 383, 398-99 (3d Cir.2006). Mandamus lies only when there is no other remedy, Mallard v. U.S. Dist. Court for the S. Dist. of Iowa, 490 U.S. 296, 309, 109 S.Ct. 1814, 104 L.Ed.2d 318 (1989), and thus may not be used as a mere substitute for appeal. In re: Diet Drugs Prods. Liab. Litig., 418 F.3d 372, 379 (3d Cir.2005). To the extent that Dougherty challenges the District Court’s determination that he did not properly serve the defendants, thus precluding a default judgment, mandamus is not appropriate for at least two reasons. First, he can raise the issue on appeal. Second, he cannot show that he has an indisputable right to entry of a default because it appears that the District Court’s exposition of the pertinent law is correct. See Fed.R.Civ.P. 4; Pa. R. Civ. P. 400. To the extent that his petition includes a challenge to the denial of his motion for reconsideration, mandamus is not appropriate for the same reasons.

We also decline to order Judge Caldwell’s recusal. “The test for recusal under [28 U.S.C] § 455(a) is whether a reasonable person, with knowledge of all the facts, would conclude that the judge’s impartiality, might reasonably be questioned.” In re: Kensington Int’l Ltd., 368 F.3d 289, 301 (3d Cir.2004). Dougherty argues that Judge Caldwell’s denial of the default judgment motions and eight-day delay in ruling demonstrate the judge’s bias and evince an attempt to sabotage Dougherty’s case by wasting portions of the 120-day period during which he can properly serve the defendants. Adverse rulings, without more, are insufficient to warrant recusal under 28 U.S.C. § 455. See Liteky v. United States, 510 U.S. 540, 555, 114 S.Ct. 1147, 127 L.Ed.2d 474 (1994). Although Dougherty contends that it took eight days for the District Court to rule on his motions for default, we note that Judge Caldwell’s order was entered on the docket only two days after the second, properly-filed motion was submitted. Dougherty points to no authority suggesting that such a delay is indicative of judicial bias.

The motion to supplement is granted, but for the foregoing reasons, we will deny Dougherty’s petition. 
      
      . Dougherty first sought Judge Caldwell's re-cusal in his mandamus petition. He then filed a recusal motion in the District Court. Dougherty attached a copy of the District Court order denying that motion to his motion to supplement. Although a mandamus petition may be used to challenge a district court's denial of a 28 U.S.C. § 455 recusal motion, see In re: Kensington Int'l Ltd., 368 F.3d 289, 300-01 (3d Cir.2004), Dougherty is not entitled to that remedy for the reasons discussed below.
